Central Regional Report 1
Oklahoma Comprehensive Water Planavailability and potential shortages are documented in the OCWP Physical Water Supply Availability Report. Statewide water demand projection methods and results are presented in the Water Demand Forecast Report. Permitting availability was evaluated based on the OWRB’s administrative protocol and documented in the Water Supply Permit Availability Report. All supporting documentation can be found on the OWRB’s website.federal agency staff, industry representatives, and stakeholder groups for each demand sector. Surface water supply data for each of the 82 basins used 58 years of publicly-available daily streamflow gage data collected by the USGS. Groundwater resources were characterized using previously-developed assessments of groundwater aquifer storage and recharge rates.
Additional information gained during the development of the 2012 Update is provided in various OCWP supplemental reports. Assessments of statewide physical water
The Oklahoma Comprehensive Water Plan (OCWP) was originally developed in 1980 and last updated in 1995. With the specific objective of establishing a reliable supply of water for state users throughout at least the next 50 years, the current update represents the most ambitious and intensive water planning effort ever undertaken by the state. The 2012 OCWP Update is guided by two ultimate goals:
Provide safe and dependable water supply 1. for all Oklahomans while improving the economy and protecting the environment.
Provide information so that water 2. providers, policy makers, and water users can make informed decisions concerning the use and management of Oklahoma’s water resources.
In accordance with the goals, the 2012 OCWP Update has been developed under an innovative parallel-path approach: inclusive and dynamic public participation to build sound water policy complemented by detailed technical evaluations.
Also unique to this update are studies conducted according to specific geographic boundaries (watersheds) rather than political boundaries (counties). This new strategy involved subdividing the state into 82 surface water basins for water supply availability analysis (see the OCWP Physical Water Supply Availability Report). Existing watershed boundaries were revised to include a United States Geological Survey (USGS) stream gage at or near the basin outlet (downstream boundary), where practical. To facilitate consideration of regional supply challenges and potential solutions, basins were aggregated into 13 distinct Watershed Planning Regions.
This Watershed Planning Region Report, one of 13 such documents prepared for the 2012 OCWP Update, presents elements of technical studies pertinent to the Central Region. Each regional report presents information from both a regional and multiple basin perspective, including water supply/demand analysis results, forecasted water supply shortages, potential supply solutions and alternatives, and supporting technical information.
Integral to the development of these reports was the Oklahoma H2O model, a sophisticated database and geographic information system (GIS) based analysis tool created to compare projected water demand to physical supplies in each of the 82 OCWP basins statewide. Recognizing that water planning is not a static process but rather a dynamic one, this versatile tool can be updated over time as new supply and demand data become available, and can be used to evaluate a variety of “what-if” scenarios at the basin level, such as a change in supply sources, demand, new reservoirs, and various other policy management scenarios.
Primary inputs to the model include demand projections for each decade through 2060, founded on widely-accepted methods and peer review of inputs and results by state and
Introduction
The primary factors in the determination of reliable future water supplies are physical supplies, water rights, water quality, and infrastructure. Gaps and depletions occur when demand exceeds supply, and can be attributed to physical supply, water rights, infrastructure, or water quality constraints.
As a key foundation of OCWP technical work, a computer-based analysis tool, “Oklahoma H2O,” was created to compare projected demands with physical supplies for each basin to identify areas of potential water shortages.
Regional Overview
The Central Watershed Planning Region includes nine basins (for reference, numbered 50, 51, 56-58, 60-62, and 64). The region is located in the Central Lowland physiography province, encompassing 10,142 square miles in central Oklahoma, spanning from southern Woods County to Hughes and Pontotoc Counties in the southeastern portion of the region and including all or portions of Alfalfa, Woodward, Garfield, Major, Kingfisher, Logan, Blaine, Dewey, Creek, Lincoln, Okmulgee, Canadian, Oklahoma, Okfuskee, Caddo, Seminole, Pottawatomie, Grady, Cleveland, McClain, and Garvin Counties.
The region displays many of the physical diversities of the state. The extremes range from the metropolitan areas of Oklahoma City in Oklahoma County to the more forested areas of the southeast, the open farmland in the central and western areas, and the sand hills in the western portion of the region.
The region’s climate is moist and sub-humid with the mean annual temperature ranging from 59° F to 62° F. Annual average precipitation ranges from 26 inches in the northwest to 46 inches in the southeastern corner. Annual lake evaporation ranges from 50 to 62 inches and exceeds precipitation. Frequent droughts cause severe crop damage while severe flooding also occurs as the result of concentrated areas of heavy precipitation. Thunderstorms accompanied by high winds, hail, and heavy rain increase the likelihood of flash flooding, emphasizing the necessity of watershed protection and flood prevention projects.
The largest cities in the region include Oklahoma City (2010 population of 501,450), Norman (109,865), Edmond (79,562), Midwest City (56,886), and Moore (52,621). The greatest demand is from Municipal and Industrial water use.
By 2060, this region is projected to have a total demand of 442,890 acre-feet per year (AFY), an increase of approximately 107,250 AFY (32%) from 2010.2 Central Regional Report
Oklahoma Comprehensive Water Planand their tributaries to provide public water supply, flood control, and recreation. There are two major federal reservoirs in the Central Region: Arcadia, built by the U.S. Army Corps of Engineers and Thunderbird, constructed by the Bureau of Reclamation. Large municipal water supply lakes in the region include Oklahoma City’s three area lakes—Overholser, Stanley Draper, and Hefner. There are 16 additional significant lakes in the region with normal storage ranging from 709 AF (El Reno Lake) to 23,000 AF (Lake Konawa). Surface water in Basins 50 and 51 is fully allocated, limiting diversions to existing permitted amounts. All other basins in the region are expected to have available surface water for new permits to meet local demand through 2060. Surface water quality in the region is variable and considered poor in several basins relative to other basins in the state. Multiple rivers, creeks, and reservoirs
The Central Region accounts for 18% of the state’s total water demand. The largest demand sectors are Municipal and Industrial (58% of the region’s overall 2010 demand), Crop Irrigation (16%), and Thermoelectric Power (14%).
Water Resources & Limitations
Surface Water
Surface water supplies, including reservoirs, are used to meet 56% of the Central Region’s demand. Surface water supply shortages are expected by 2020 in all basins in the region, except Basins 60 and 62. Shortages are expected to have a moderate to high probability of occurring. The region is supplied by five major rivers: the Canadian, Cimarron, Little, Deep Fork, and North Canadian. Large reservoirs have been built on these rivers
Central Regional Summary in the region are impaired for Public and Private Water Supply use and Agricultural use due to high levels of oil and grease, chloride, total dissolved solids (TDS), and chlorophyll a.
Alluvial Groundwater
Alluvial groundwater is used to meet 23% of the demand in the region. The majority of currently permitted groundwater withdrawals in the region are from the Cimarron River, Canadian River, and North Canadian River alluvial aquifers. Each has more than 2.7 million AF of storage in the region. There are also substantial water rights in the Gerty Sand alluvial aquifer and multiple minor aquifers. If alluvial groundwater continues to supply a similar portion of demand in the future, storage depletions from these aquifers may occur throughout the year. The largest storage depletions are projected to occur in the summer. The availability of permits is not expected to constrain the use of alluvial groundwater supplies to meet local demand through 2060.
Synopsis
The Central Watershed Planning Region relies primarily on surface water supplies (including reservoirs), out-of-basin supplies, and to a lesser extent alluvial and bedrock groundwater.
It is anticipated that water users in the region will continue to rely on these sources to meet future demand.
By 2020, surface water supplies may be insufficient at times to meet demand in all basins in the region, except Basins 60 and 62.
By 2020, alluvial and bedrock groundwater storage depletions may occur and eventually lead to higher pumping costs, the need for deeper wells, and potential changes to well yields or water quality.
To reduce the risk of adverse impacts on water supplies, it is recommended that gaps and storage depletions be decreased where economically feasible.
Additional conservation could reduce surface water gaps and groundwater storage depletions, eliminating bedrock groundwater depletions in Basin 50 and alluvial groundwater storage depletions in Basins 50 and 62.
Aquifer storage and recovery in Basins 50 and 51 could be considered to store variable surface water supplies, increase groundwater storage, and reduce adverse effects of localized storage depletions.
Surface water alternatives, such as groundwater sources, out-of-basin supplies, and/or developing new reservoirs, could mitigate gaps without major impacts to groundwater storage.

Central Region
Bedrock Groundwater
Bedrock groundwater is used to meet 21% of the demand in the region. The majority of currently permitted bedrock groundwater withdrawals in the region are from the Garber-Wellington aquifer. This aquifer has more than 55.6 million AF of storage in the Central Region. There are also substantial water rights in multiple major and minor aquifers. Recharge to major aquifers is expected to be sufficient to meet some of the region’s bedrock groundwater demand through 2060. Bedrock groundwater storage depletions may occur in Basins 50, 51, 57, and 64, typically by 2020. The availability of permits is not expected to constrain the use of bedrock groundwater supplies to meet local demand through 2060. However, an ongoing multi-year study of the Garber-Wellington may result in a change to the 2 AFY/acre share currently allowed under temporary permit.
Water Supply Limitations
Surface water limitations were based on physical availability, water supply availability for new permits, and water quality. Groundwater limitations were based on the total size and rate of storage depletions in major aquifers. Groundwater permits are not expected to constrain the use of groundwater through 2060, and insufficient statewide groundwater quality data are available to compare basins based on groundwater quality. Basins with the most significant water supply challenges statewide are indicated by a red box. The remaining basins with surface water gaps or groundwater storage depletions were considered to have potential limitations (yellow). Basins without gaps and storage depletions were considered to have minimal limitations (green). Detailed explanations of each basin’s supplies are provided in individual basin summaries and supporting data and analysis.4 Central Regional Report Oklahoma Comprehensive Water Plan
Water Supply Options
To quantify physical surface water gaps and groundwater storage depletions through 2060, use of existing out-of-basin and local supplies was assumed to continue in current (2010) proportions. Surface water supplies, reservoirs, out-of-basin supplies, and bedrock groundwater supplies are expected to continue to supply the majority of demand in the Central Region. Surface water users may have physical surface water supply shortages (gaps) in the future, except in Basins 60 and 62. Alluvial groundwater storage depletions of major and minor aquifers are also projected in the future and may occur in most basins in the region by 2020. Bedrock groundwater storage depletions may occur in Basins 50, 51, 57, and 64. The development of additional alluvial and bedrock groundwater supplies could be an effective a long-term water supply option, except in portions of the North Canadian River alluvial aquifer.
Water conservation could aid in reducing projected gaps and groundwater storage depletions or delaying the need for additional infrastructure. Moderately expanded conservation activities could reduce gaps and storage depletions throughout the region, and could eliminate bedrock groundwater storage depletions in Basin 50 and alluvial groundwater storage depletions in Basin 62. Future reductions could occur from substantially expanded conservation activities. These measures would require a shift from crops with high water demand (e.g., corn for grain and forage crops) to low water demand crops (e.g., sorghum for grain or wheat for grain) along with increased efficiency and increased public water supplier conservation. In basins with lower frequencies of shortages, temporary drought management measures may be an effective water supply option.
New reservoirs and expanded use of existing reservoirs could enhance the dependability of surface water supplies and reduce gaps in some basins in the region. Several small municipal reservoirs may have unpermitted yield available for new users; however, these supplies are small compared to the demand in the region. Oklahoma City currently receives substantial supplies from the Blue-Boggy Watershed Planning Region via the Atoka pipeline. The City of Ada also receives out-of-basin supplies from Byrds Mill Spring and the Arbuckle-Simpson aquifer in the Blue-Boggy Region. These out-of-basin supplies are expected to continue to provide water to the region in the future. The OCWP Reservoir Viability Study, which evaluated the potential for reservoirs throughout the state, identified 16 potentially viable sites in the Central Region. These water sources could serve as in-basin storage or out-of-basin supplies to provide additional supplies to reduce the region’s and surrounding regions’ surface water gaps and groundwater storage depletions. However, due to the distance of these potential reservoirs to demand points in each basin, this water supply option may not be cost-effective for many users.
The projected growth in surface water use could instead be supplied in part by increased use of the Garber-Wellington aquifer, Canadian River aquifer, Cimarron River aquifer or the North Canadian River aquifer, which would result in small or minimal increases in projected groundwater storage depletions. However, these aquifers do not underlie the entire region and water quality may limit their use. Also, ongoing studies to determine the maximum annual yield and equal proportionate share for the Garber-Wellington aquifer may change the current amount (2 AFY/acre) of water allowed under temporary permits.
Effectiveness of water supply options in each basin in the Central Region. This evaluation was based upon results of physical water supply availability analysis, existing infrastructure, and other basin-specific factors.

No known information is annotated as “---”(70 miles long, tributary to the Little River). The Canadian River and its tributaries are located in Basins 56, 57, 58, 61, and 62. The river typically experiences high levels of chloride and total dissolved solids.
The mainstem of the Cimarron River runs for 150 miles through Basin 64. Major tributaries include Turkey Creek (70 miles long) and Cottonwood Creek (60 miles long). Water quality is degraded by naturally occurring salt sources in the upper reaches near the Harper/Woods County line.
Water Supply
Physical Water Availability
Surface Water Resources
Surface water supply has historically been used to meet just over half of the demand in the Central Region. The region’s major rivers include the Canadian, Cimarron, Little, Deep Fork, and North Canadian. Many streams in this region experience a wide range of flows, including both periodic no-flow conditions and flooding events.
The North Canadian River (320 miles long in the Central Region) flows from the Panhandle Region through Basins 50 and 51 in the Central Region. Total dissolved solids (TDS) and chloride levels are relatively high and Oklahoma City wastewater return flows constitute a large percentage of the North Canadian River’s total flow.
The Deep Fork River originates in the Central Region and is 140 miles long in Basin 60. The river is generally of fair quality with moderate mineral content. However, the chloride content may reach high levels during certain periods of the year.
The Canadian River (190 miles long in the Central Region) enters the Central Region from the West Central Region. Major tributaries in the region include Walnut Creek (25 miles long), the Little River (110 miles long), and Salt Creek
As important sources of surface water in Oklahoma, reservoirs and lakes help provide dependable water supply storage, especially when streams and rivers experience periods of low seasonal flow or drought.Oklahoma Comprehensive Water Plan Central Regional Report 7
In the Central Region, streamflow is generally
intermittent. Existing reservoirs in the region
increase the dependability of surface water
supply for many public water systems and other
users. Some reservoirs provide terminal storage
for out-of-basin supplies. There are two major
federal reservoirs in the region. Lake Arcadia
in Basin 60 was completed in 1986 on the Deep
Fork River by the U.S. Army Corps of Engineers
for water supply, recreation, and fish and
wildlife purposes. The lake provides 12,320 AFY
of dependable yield, which is allocated to the
City of Edmond. Lake Thunderbird in Basin 62
was built in 1965 on the Little River by the U.S.
Bureau of Reclamation. Project purposes include
flood control, water supply, recreation, and fish
and wildlife. Most of Thunderbird’s water supply
yield is allocated to the Central Oklahoma Master
Conservancy District, which supplies municipal
and industrial water to its member cities
(Norman, Midwest City and Del City).
There are five major municipal lakes in the
Central Region. Three were constructed by
the City of Oklahoma City, one by the City
of Shawnee, and the fifth by the NRCS and
is operated by the Pottawatomie County
Development Authority. Lake Stanley Draper, in
Basin 62, was constructed in 1962 by Oklahoma
City and is located on East Elm Creek. The
impoundment is used primary as terminal storage
for water conveyed from Atoka Lake and McGee
Creek in the Blue-Boggy Watershed Planning
Region via the 90 mgd Atoka Pipeline. While
Lake Stanley Draper has little dependable yield
of its own, it can provide a dependable yield of
about 86,000 AFY comprised of deliveries from
Atoka and McGee Creek minus losses.
Oklahoma City’s other two lakes in the Central
Region, Lake Overholser in Basin 51 and Lake
Hefner in Basin 64, are operated to utilize the
City’s water right allocations from Canton Lake
in the Panhandle Watershed Planning Region
and the North Canadian River. Lake Overholser
was built in 1919 on the North Canadian River
for the purposes of water supply and recreation.
The lake has a dependable yield of 5,000 AFY,
which is supplemented by releases from Canton
Lake via the North Canadian River. Lake Hefner
was constructed on Bluff
Creek in 1943 by Oklahoma
City for the purposes of
offstream water supply
storage and recreation.
The lake serves as terminal
storage for diversions from
the North Canadian
River and releases
from Canton
Lake via a canal
that diverts water
from the river near
Lake Overholser. The system
provides a dependable yield of 80,000
AFY to Oklahoma City and is fully
allocated.
Shawnee Twin Lakes were
constructed by the City of Shawnee
on South Deer Creek in Basin 50. These
two lakes, one constructed in 1935 and one
in 1960, are connected by a canal and have
a combined yield of 4,400 AFY that is fully
allocated to the City of Shawnee. Wes Watkins
Reservoir, also in Basin 50, was constructed
in 1997 by the NRCS for the purposes of flood
control, water supply and recreation. The
lake is operated by the Pottawatomie County
Development Authority.
Some of the other significant lakes in the region
include: Lake Wetumka and Tecumseh Lake in
Basin 50; El Reno Lake in Basin 51; Konawa and
Holdenville Lakes in Basin 56; Purcell Lake in
Basin 57; Bell Cow, Meeker, Prague City, Stroud,
Chandler, and Okemah Lakes in Basin 60; and
Guthrie and Liberty Lakes in Basin 64.
There are many other small Natural Resources
Conservation Service (NRCS), municipal and
privately owned lakes in the region that provide
water for public water supply, agricultural water
supply, watershed protection, flood control and
recreation.
Surface Water Resources
Central Region
Major reservoirs in the Central Region include Arcadia, Thunderbird, Overholser, Hefner,
Shawnee Twin Lakes, Wes Watkins, and Stanley Draper. These lakes may serve multiple
purposes, such as water supply, irrigation, recreation, hydropower generation, and flood
control. Reservoirs designed for multiple purposes typically possess a specific volume of water
storage assigned for each purpose.

Annual streamflow in 2060 was estimated using historical gaged flow and projections of increased surface water use from 2010 to 2060.
Surface Water Flows (1950-2007)
Central Region
Surface water sources supply about half of the demand in the Central Region. Surface water gaps can occur due to seasonal, long-term hydrologic (drought), or localized variability in surface water flows. Several large reservoirs have been constructed to reduce the impacts of drier periods on surface water users.
Water Supply Availability Analysis
For OCWP physical water supply availability analysis, water supplies were divided into three categories: surface water, alluvial aquifers, and bedrock aquifers. Physically available surface water refers to water currently in streams, rivers, lakes, and reservoirs.
The range of historical surface water availability, including droughts, is well-represented in the Oklahoma H2O tool by 58 years of monthly streamflow data (1950 to 2007) recorded by the U.S. Geological Survey (USGS). Therefore, measured streamflow, which reflects current natural and human created conditions (runoff, diversions and use of water, and impoundments and reservoirs), is used to represent the physical water that may be available to meet projected demand.
The estimated average and minimum annual streamflow in 2060 were determined based on historic surface water flow measurements and projected baseline 2060 demand (see Water Demand section). The amount of streamflow in 2060 may vary from basin-level values, due to local variations in demands and local availability of supply sources. The estimated surface water supplies include changes in historical streamflow due to increased upstream demand, return flows, and increases in out-of-basin supplies from existing infrastructure. Permitting, water quality, infrastructure, non-consumptive demand, and potential climate change implications are considered in separate OCWP analyses. Past reservoir operations are reflected and accounted for in the measured historical streamflow downstream of a reservoir. For this analysis, streamflow was adjusted to reflect interstate compact provisions in accordance with existing administrative protocol.
The amount of water a reservoir can provide from storage is referred to as its yield. The yield is considered the maximum amount of water a reservoir can dependably supply during critical drought periods. OCWP physical availability analyses considered the unused yield of existing reservoirs. Future potential reservoir storage was considered as a water supply option.
Groundwater supplies are quantified by the amount of water that the aquifer holds (“stored” water) and the rate of aquifer recharge. In Oklahoma, recharge to aquifers is generally from precipitation that falls on the aquifer and percolates to the water table. In some cases, where the altitude of the water table is below the altitude of the stream-water surface, surface water can seep into the aquifer.
For this analysis, alluvial aquifers are defined as aquifers comprised of river alluvium and terrace deposits, occurring along rivers and streams and consisting of unconsolidated deposits of sand, silt, and clay. Alluvial aquifers are generally thinner (less than 200 feet thick) than bedrock aquifers, feature shallow water tables, and are exposed at the land surface, where precipitation can readily percolate to the water table. Alluvial aquifers are considered to be more hydrologically connected with streams than are bedrock aquifers and are therefore treated separately.
Bedrock aquifers consist of consolidated (solid) or partially consolidated rocks, such as sandstone, limestone, dolomite, and gypsum. Most bedrock aquifers in Oklahoma are exposed at land surface, either entirely or in part. Recharge from precipitation is limited in areas where bedrock aquifers are not exposed.
For both alluvial and bedrock aquifers, this analysis was used to predict potential groundwater depletions based on the difference between the groundwater demand and recharge rate. While potential storage depletions do not affect the permit availability of water, it is important to understand the extent of these depletions.Central Regional Oklahoma Comprehensive Water Plan Report 9
downward to sandy clay, sand, and fine gravel, Maximum thickness reaches 80 feet with well yields ranging between 100 and 200 gpm in the alluvium and 100 and 500 gpm in the terrace deposits. The terrace deposits are overlain by sand dunes. The water is very hard and is classified as calcium magnesium bicarbonate type. Extensive pumping can make this formation susceptible to salt water intrusion.
The Canadian River alluvial aquifer underlies portions of Basins 51, 56, 57, 58, 61, and 62. The formation consists of clay and silt downgrading to fine- to coarse-grained sand with lenses of basal gravel. Formation thicknesses range from 20 to 40 feet in the alluvium with a maximum of 50 feet in the terrace deposits. Yields in the alluvium range between 100 and 400 gpm and between 50 and 100 gpm in the terrace. Although the water is a very hard calcium bicarbonate type with TDS concentrations of approximately 1,000 mg/L, it is generally suitable for most municipal and industrial uses.
The North Canadian River alluvial aquifer underlies portions of Basins 50, 51, and 64.The formation consists of fine- to coarse-grained sand with minor clay and silt and local lenses of basal gravel overlain by dune sand. Formation thickness averages 30 feet in the alluvium with a maximum of 300 feet in the terrace deposits. Yields range between 300 and 600 gpm in the alluvium and 100 to 300 gpm in the terrace formations. The water is a very hard calcium bicarbonate type with TDS concentrations of up to 1,000 mg/L.
The Cimarron River alluvial aquifer underlies a portion of Basin 64. The formation tends to consist of silt and clay deposits changing
Groundwater Resources
Three major bedrock aquifers underlie the Central Watershed Planning Region: Rush Springs, Garber-Wellington, and Vamoosa-Ada. Five major alluvial aquifers underlie the region: Canadian River, Cimarron River, Enid Isolated Terrace, Gerty Sand, and North Canadian River.
The Garber-Wellington aquifer underlies portions of Basins 50, 51, 56, 58, 60, 61, 62, and 64. The formation consists of fine-grained sandstone interbedded with siltstone and shale. Depth to water varies from less than 100 feet to 250 feet; saturated thickness ranges from 150 to 650 feet. Wells generally yield from 200 to 400 gpm. Water quality is generally good, but in some areas, concentrations of nitrate, arsenic, chromium, and selenium may exceed drinking water standards.
The Vamoosa-Ada aquifer underlies portions of Basins 50, 56, 60, 61, and 62. The formation consists of 125 to 1,000 feet of interbedded sandstone, shale, and conglomerate. Wells commonly yield 25 to 150 gpm. Water quality is generally good and suitable for use as public supply, although iron infiltration and hardness are problems in some areas and there are local problems due to contamination resulting from past oil and gas activities.
The Rush Springs aquifer underlies a portion of Basin 58. The formation consists of a fine-grained sandstone aquifer with some shale, dolomite, and gypsum. Thickness of the aquifer ranges from 200 to 300 feet. Wells commonly yield 25 to 400 gpm. The water tends to be very hard, requiring water softening to address aesthetic issues for public water supply use. In some areas nitrate and sulfate concentrations exceed drinking water standards, limiting its use for drinking water.
Withdrawing groundwater in quantities exceeding the amount of recharge to the aquifer may result in reduced aquifer storage. Therefore, both storage and recharge were considered in determining groundwater availability.
Areas without delineated aquifers may have groundwater present. However, specific quantities, yields, and water quality in these areas are currently unknown.

1 Bedrock aquifers with typical yields greater than 50 gpm and alluvial aquifers with typical yields greater than 150 gpm are considered major.
Permits to withdraw groundwater from aquifers (groundwater basins) where the maximum annual yield has not been set are “temporary” permits that allocate 2 AFY/acre. The temporary permit allocation is not based on storage, discharge or recharge amounts, but on a legislative (statute) estimate of maximum needs of most landowners to ensure sufficient availability of groundwater in advance of completed and approved aquifer studies. As a result, the estimated amount of Groundwater Available for New Permits may exceed the estimated aquifer storage amount. For aquifers (groundwater basins) where the maximum annual yield has been determined (with initial storage volumes estimated), updated estimates of amounts in storage were calculated based on actual reported use of groundwater instead of simulated usage from all lands.10 Central Regional Report Oklahoma Comprehensive Water Plan
Groundwater Resources
Central Region
The Gerty Sand alluvial aquifer underlies a portion of Basin 56. The formation consists of gravel, sand, silt, clay, and volcanic ash. The saturated thickness varies from 5 to 75 feet, averaging 28 feet. Depth to water ranges from 10 to 110 feet. Typical well yields vary from 100 to 450 gpm with some wells yielding as much as 850 gpm. Water quality is fair to good and moderately hard with TDS values usually less than 1,000 mg/L.
The Enid Isolated Terrace alluvial aquifer underlies a small portion of Basin 64. The formation is composed of terrace deposits that consist of discontinuous layers of clay, sandy clay, sand, and gravel.
Minor bedrock aquifers in the region include the East-Central Oklahoma, El Reno, and North-Central Oklahoma aquifers. Minor alluvial aquifers include the Fairview Isolated Terrace, Isabella Isolated Terrace, and Loyal Isolated Terrace. Minor aquifers may have a significant amount of water in storage and high recharge rates, but generally low yields of less than 50 gpm per well. Groundwater from minor aquifers is an important source for domestic and stock water use for individuals in outlying areas not served by rural water systems, but yields might be insufficient for high volume users.Oklahoma Comprehensive Water Plan Central Regional Report 11
Surface Water Permit Availability
Central Region
There is no surface water available for new permits in Basins 50 and 51, but projections indicate that there will be surface water available for new permits through 2060 in all other basins in the Central Region.
Projections indicate that the use of groundwater to meet in-basin demand is not expected to be limited by the availability of permits through 2060 in the Central Region.
Groundwater Permit Availability
Central Region
Permit Availability
For the OCWP water availability analysis, “permit availability” pertains to the amount of water that could be made available for withdrawals under permits issued in accordance with Oklahoma water law.
Projections indicate that there will be no surface water available for new permits in Basins 50 and 51, but surface water will be available for new permits through 2060 in all other basins in the Central Region. For groundwater, equal proportionate shares in the Central Region range from 0.5 acre-feet per year (AFY) per acre to 2 AFY per acre.
If water authorized by a stream water right is not put to beneficial use within the specified time, the OWRB may reduce or cancel the unused amount and return the water to the public domain for appropriation to others.
Water Use Permitting in Oklahoma
Oklahoma stream water laws are based on riparian and prior appropriation doctrines. Riparian rights to a reasonable use of water, in addition to domestic use, are not subject to permitting or oversight by the OWRB. An appropriative right to stream water is based on the prior appropriation doctrine, which is often described as “first in time, first in right.” If a water shortage occurs, the diverter with the older appropriative water right will have first right among other appropriative right holders to divert the available water up to the authorized amount.
The permit availability of surface water is based on the average annual flow in the basin, the amount of water that flows past the proposed diversion point, and existing water uses upstream and downstream in the basin. The permit availability of surface water at the outlet of each basin in the region was estimated through OCWP technical analyses. The current allocated use for each basin is also noted to give an indication of the portion of the average annual streamflow used by existing water right holders. A site-specific analysis is conducted before issuing a permit.
Groundwater permit availability is generally based on the amount of land owned or leased that overlies a specific aquifer (groundwater basin). State law provides for the OWRB to conduct hydrologic investigations of groundwater basins and to determine amounts of water that may be withdrawn. After a hydrologic investigation has been conducted on a groundwater basin, the OWRB determines the maximum annual yield of the basin. Based on the “equal proportionate share”—defined as the portion of the maximum annual yield of water from a groundwater basin that is allocated to each acre of land overlying the basin—regular permits are issued to holders of existing temporary permits and to new permit applicants. Equal proportionate shares have yet to be determined on many aquifers in the state. For those aquifers, “temporary” permits are granted to users allocating two acre-feet of water per acre of land per year. When the equal proportionate share and maximum annual yield are approved by the OWRB, all temporary permits overlying the studied basin are converted to regular permits at the new approved allocation rate. As with stream water, a groundwater permit grants only the right to withdraw water; it does not ensure yield.12 Central Regional Report Oklahoma Comprehensive Water Plan
Water Quality
Water quality of the Central Watershed Planning
Region is defined by numerous minor and major
water supply reservoirs and the middle Cimarron
and lower Canadian River watersheds. The area
is co-dominated by two ecoregions, the Central
Great Plains (CGP) to the west and the Cross
Timbers (CT) to the east. Several additional
ecoregions intersect the periphery of the planning
region, but their impact is minimal and they will
not be addressed in this discussion.
The western half of the planning region is
characterized by the Prairie Tablelands and
several other intervening CGP ecoregions, the
Pleistocene Sand Dunes/Sandsage Grassland,
and Gypsum Hills. The Cimarron and North
Canadian Rivers drain the area from northwest
to southeast, and the Canadian River intersects
the area in the south. The Prairie Tablelands are
nearly level, underlain by shale, sandstone, and
siltstone. They are dominated by cropland with
dense mixed grass prairies. Streams are typically
turbid and silt-dominated with some sand,
lying in broad, shallow, low gradient channels
with highly incised banks. The tributaries of
the major rivers best exemplify water quality
in the tablelands. These include Buggy Creek
along the Canadian, and from west to east on the
Cimarron, Eagle Chief, Turkey, Kingfisher, and
Cottonwood Creeks. Salinity is high throughout
the watersheds. Mean conductivities range from
1,029 μS/cm on Cottonwood Creek to near 2,300
μS/cm on Kingfisher Creek, while Buggy Creek
is 1,100 μS/cm. Nutrient concentrations are also
high. Mean concentrations of total phosphorus
(TP) and total nitrogen (TN) range from 0.18
and 2.05 ppm on Kingfisher Creek to 0.98 and
4.08 ppm on Cottonwood Creek. Buggy Creek
is similar with mean TP and TN of 0.38 and 2.0
ppm. Water clarity is poor to very poor, with
mean turbidity ranging from 65 NTU
on Eagle Chief Creek to 184 NTU on
Cottonwood Creek; Buggy Creek
is 160 NTU. Ecological diversity
is average and highly impacted by
siltation/sedimentation, habitat
degradation, and channelization.
Conversely, the Pleistocene
Sand Dunes have more
permeable sandy soils interlaced
with springs and inter-dune
wetlands. Streams have incised,
highly erodible banks but are
typically sandy. The northern and
eastern banks of the major river
systems are influenced heavily by
the features and are typically sandier
than many of their tributaries. The
Cimarron and North Canadian best
exemplify the area, as well as El
Reno Lake in the North Canadian
watershed. Salinity on the Cimarron
is very high and steadily decreases
from west to east. Near Waynoka,
mean conductivity is nearly 29,000
μS/cm, but at Guthrie, it decreases
to 8,730 μS/cm. Salinity on the
North Canadian (including El
Reno Lake) and Canadian is much
lower with mean conductivities
of 1,350-1,400 μS/cm. Nutrient
concentrations increase steadily
along the Cimarron. Near Waynoka,
the river is mesotrophic, with low
TP and TN mean concentrations
of 0.05 and 0.69 ppm. The river
gradually becomes eutrophic to
hyper-eutrophic; at Guthrie, TP and
TN increase to 0.36 and 1.95 ppm.
The North Canadian and Canadian
are also hyper-eutrophic, with TP ranging from
0.20-0.22 ppm and TN from 0.99-1.24 ppm. El
Reno Lake is hyper-eutrophic and nitrogen-limited.
Water clarity is excellent to average on
the Cimarron with mean turbidity values of 6
Lake Trophic Status
A lake’s trophic state, essentially a measure of its
biological productivity, is a major determinant of
water quality.
Oligotrophic: Low primary productivity and/or low
nutrient levels.
Mesotrophic: Moderate primary productivity with
moderate nutrient levels.
Eutrophic: High primary productivity and nutrient
rich.
Hypereutrophic: Excessive primary productivity
and excessive nutrients.
The Central Planning Region is a transitional area between the Central Great Plains and
Cross Timbers. Water quality is highly influenced by both geology and land use practices,
and is generally poor to good depending on drainage and location.

NTU near Waynoka and 33 NTU near Guthrie.
The North Canadian has good clarity (18 NTU)
while the Canadian is average (40 NTU). El
Reno Lake has poor clarity. Ecological diversity
is good in the Canadian watersheds but can be
impacted by habitat degradation, channelization,
and sedimentation. Conversely, diversity in the
Cimarron is low and is naturally impacted by
higher than normal salinity and also by flow
modification and sedimentation.
The Gypsum Hills are characterized by
breaks, escarpments, gorges, ledges, caves,
and canyons. Geological features were
formed by the differential erosion of
underlying gypsum, shale, dolomite,
fine sand, and rock salt. The features
create flora and fauna that are unique
within the CGP. The area is covered by
mixed grass prairie and intermittent tree groves.
Streams are typically bedrock/gravel/cobble,
with habitat that is typically more diverse than
surrounding areas. Griever Creek has relatively
high salinity (mean conductivity = 2,870
μS/cm), and poor water clarity (58 NTU).
However, nutrient concentrations are low
with mean TP of 0.11 and TN of 0.70 ppm.
The Northern Cross Timbers extends from
roughly the center of the Oklahoma City
metropolitan area south to Purcell and
east through the remainder of the region.
The Northern Timbers is densely forested
and covered by a variety of flora including
oak savanna, scrub oak forest, eastern
red cedar, and intervening grasslands.
Land use is mixed with rangeland,
cropland, urban, and intense oil/natural
gas production, which has led to higher
than normal salinity in some watersheds.
Streams are typically contained in shallow,
sandy channels and are normally moderately
to heavily incised. However, deep pools, riffles,
and rocky substrates exist in various parts
of the area. Ecological diversity is mixed and
can be affected by habitat degradation, flow
modification, channelization, and sedimentation/
siltation. The area is best exemplified by the
lower North Canadian and Canadian River
watersheds, including the Deep Fork of the
Water Quality Standards Implementation
Central Region
BUMP monitoring sites and streams with TMDL studies completed or underway. The
Oklahoma Conservation Commission has begun a watershed implementation project on
Lake Thunderbird to address non-point source runoff through low-impact development. The
Oklahoma Department of Environmental Quality has completed TMDL studies on North
Canadian River, Turkey Creek, and Little Turkey Creek. Several other TMDL studies are
underway or scheduled.
Water Quality Standards and
Implementation
The Oklahoma Water Quality Standards
(OWQS) are the cornerstone of the
state’s water quality management
programs. They are a set of rules
promulgated under the federal Clean
Water Act and state statutes to maintain
and protect the quality of state waters.
The OWQS designate beneficial uses
for streams, lakes and other bodies of
surface water, and for groundwater
that has a mean concentration of Total
Dissolved Solids of 10,000 milligrams
per liter or less. Beneficial uses are the
activities for which a waterbody can
be used based on physical, chemical,
and biological characteristics as well as
geographic setting, scenic quality, and
economic considerations. Beneficial
uses include such categories as Fish and
Wildlife Propagation, Public and Private
Water Supply, Primary (or Secondary)
Body Contact Recreation, Agriculture,
and Aesthetics. The OWQS also contain
standards for maintaining and protecting
these uses. The purpose of the OWQS
is to promote and protect as many
beneficial uses as are attainable and to
assure that degradation of existing quality
of waters of the state does not occur.
The OWQS are applicable to all activities
which may affect the water quality of
waters of the state, and are to be utilized
by all state environmental agencies in
implementing their programs to protect
water quality. Some examples of these
implementation programs are: permits
for point source (e.g. municipal and
industrial) discharges into waters of the
state; authorizations for waste disposal
from concentrated animal feeding
operations; regulation of runoff from
nonpoint sources; and corrective actions
to clean up polluted waters.

North Canadian and the Little River, as well as numerous municipal and regional water supply lakes including Arcadia, Bell Cow, Chandler, Holdenville, Konawa, Meeker, Okemah, Prague City, Shawnee Twins, Stanley Draper, Stroud, Thunderbird, Tecumseh, Wes Watkins, and Wetumka. Stream salinity, although still considered high, decreases notably from the upper portions of the watersheds. The Canadian watershed is higher with a mean conductivity of 975-1,070 μS/cm on the mainstem and 1,210 on the Little River. The North Canadian is lower, with conductivity ranging from 720-850 μS/cm on the mainstem and 675-815 μS/cm on the Deep Fork. Reservoir salinity is typically low to moderate with some reservoirs ranging from 75-275 μS/cm while others have values as high as 350-450 μS/cm (Bell Cow and Thunderbird). Lake Konawa is high, with an approximate mean of 1,100 μS/cm. Stream nutrient concentrations are relatively high throughout the area and decrease at downstream sites as the watershed moves away from the Oklahoma City metropolitan area. The TP means are 0.31-0.36 ppm (Canadian), 0.68-0.94 ppm (North Canadian), and 0.19-0.34 ppm (Deep Fork). The TN means are 1.47-1.81 ppm (Canadian), 2.72-4.24 ppm (North Canadian), and 1.04-2.19 ppm (Deep Fork). The TP and TN means for Little River are relatively low at 0.16 and 0.83 ppm. While the Deep Fork and Little River remain oligotrophic, all other waters are hyper-eutrophic. All lakes are phosphorus limited and are mesotrophic or eutrophic (Arcadia, Bell Cow, Chandler, Konawa, Thunderbird, and Wes Watkins). Stream water clarity is nearly always poor to very poor and decreases downstream. Turbidity means are 52 NTU (Little River) 49-53 NTU (Canadian), 70-124 NTU (North Canadian), and 38-80 NTU (Deep Fork). Reservoir clarity is diverse and is categorized as poor (Meeker Secchi depth = 10 cm), average (Thunderbird = 53 cm), good (Prague City = 74 cm), and excellent (Stroud = 126 cm).
Dividing the Prairie Tablelands and Northern Cross Timbers is the Cross Timbers Transition. The transition is a hybrid mix of rough plains covered by prairie grasses and oak/elm and cedar forests, with cropland and rangeland as land uses.
Water Quality Impairments
A waterbody is considered to be impaired when its quality does not meet the standards prescribed for its beneficial uses. For example, impairment of the Public and Private Water Supply beneficial use means the use of the waterbody as a drinking water supply is hindered. Impairment of the Agricultural use means the use of the waterbody for livestock watering, irrigation or other agricultural uses is hindered. Impairments can exist for other uses such as Fish and Wildlife Propagation or Recreation.
The Beneficial Use Monitoring Program (BUMP), established in 1998 to document and quantify impairments of assigned beneficial uses of the state’s lakes and streams, provides information for supporting and updating the OWQS and prioritizing pollution control programs. A set of rules known as “use support assessment protocols” is also used to determine whether beneficial uses of waterbodies are being supported.
In an individual waterbody, after impairments have been identified, a Total Maximum Daily Load (TMDL) study is conducted to establish the sources of impairments—whether from point sources (discharges) or non-point sources (runoff). The study will then determine the amount of reduction necessary to meet the applicable water quality standards in that waterbody and allocate loads among the various contributors of pollution.
For more detailed review of the state’s water quality conditions, see the most recent versions of the OWRB’s BUMP Report, and the Oklahoma Integrated Water Quality Assessment Report, a comprehensive assessment of water quality in Oklahoma’s streams and lakes required by the federal Clean Water Act and developed by the ODEQ.
Water Quality Impairments
Central Region
Regional water quality impairments based on the 2008 Integrated Water Quality Assessment Report. Many surface waters in this region are impacted by urbanization, including increased nutrients and sediment as well as stream habitat alterations due to increases in impervious surfaces. Water from the Garber-Wellington (Central Oklahoma) aquifer is typically suited for public water supply but, in some areas, concentrations of nitrate, arsenic, chromium, and selenium exceed drinking water standards. Elevated concentrations of nitrate can occur in shallow water, which can be a concern for domestic well users. Elevated concentrations of arsenic, chromium, and selenium occur in deep parts of the aquifer, mostly affecting public water supply wells. The highest concentrations of arsenic tend to occur in the western portion of the aquifer where it is overlain by younger rocks.Oklahoma Comprehensive Water Plan Central Regional Report 15
In the central region, the major land use is urban, as much of the Oklahoma City metropolitan area overlays the ecoregion. Streams are typically rockier and less muddy than other streams in the region. Ecological diversity is higher than areas to the west but lower than regions to the east and is affected by habitat degradation, channelization, flow modifications, and sedimentation/siltation. The North Canadian and Canadian pass through the area and several major and minor water supply lakes exist there, including Guthrie, Liberty, Hefner, Overholser and Purcell. Stream salinity is high, ranging from 915 μS/cm (North Canadian) to 1,260 (Canadian). Lake salinity is moderate (Purcell = 400 μS/cm) to high (Hefner = 1,100 μS/cm). With the North Canadian having higher nutrient concentrations, rivers are hyper-eutrophic. The TP and TN mean concentrations range from 0.47-1.18 ppm and 2.70-4.31 ppm. All reservoirs are phosphorus limited, with the exception of Purcell Lake (eutrophic), and are hyper-eutrophic. Stream clarity is good on the North Canadian (34 NTU) but poor on the Canadian (80 NTU). Lake clarity is typically average (Liberty = 42 cm) to good (Hefner = 92 cm), but Overholser nears poor (32 cm).
The Central region is underlain by several major and minor bedrock and alluvial aquifers. In most alluvial aquifers, water quality is good with variable dissolved solid contents. Except for hardness and localized nitrate problems, alluvial groundwater is appropriate for domestic, irrigation, industrial, and municipal use. Alluvial aquifers are highly vulnerable to contamination from surface activities due to their high porosities and permeabilities and shallow water tables.
The Rush Springs aquifer borders the southern edge of the region. Although comparatively hard, most of the water derived from it is suitable for domestic, municipal, irrigation, and industrial use with total dissolved solids (TDS) values generally less than 500 ppm. However, sulfate and nitrate concentrations exceed drinking water standards in some areas.
The Garber-Wellington runs through the central portion of the region and underlies much of the Oklahoma City metropolitan area. Water ranges from hard to very hard, and in general, concentrations of dissolved solids, chloride, and sulfate are low. Water from the aquifer is normally suitable for public water supply, but concentrations of nitrates, sulfate, chloride, fluoride, arsenic, chromium, and selenium may exceed drinking water standards in localized areas.
The Vamoosa-Ada runs adjacent to the Garber-Wellington and underlies portions of Lincoln, Okfuskee, Seminole, and Pottawatomie Counties. Water quality is generally good, but iron infiltration and hardness are problems. Chloride and sulfate concentrations are generally low, and except for areas of local contamination resulting from past oil and gas activities, water is suitable for use as public supply.

Special OWQS provisions in place to protect surface waters. Because Wes Watkins Reservoir and Lake Wetumka are public water supply reservoirs and have relatively small watersheds, they could potentially benefit from SWS designations. This designation could provide protection from new or increased loading from point sources in the watersheds. This additional protection would also provide limits for algae (chlorophyll a) that can cause taste and odor problems and increased treatment costs.
Surface Water Protection Areas
Central Region
Surface Water Protection
The Oklahoma Water Quality Standards (OWQS) provide protection for surface waters in many ways.
Appendix B Areas are designated in the OWQS as containing waters of recreational and/or ecological significance. Discharges to waterbodies may be limited in these areas.
Source Water Protection Areas are derived from the state’s Source Water Protection Program, which analyzes existing and potential threats to the quality of public drinking water in Oklahoma.
The High Quality Waters designation in the OWQS refers to waters that exhibit water quality exceeding levels necessary to support the propagation of fishes, shellfishes, wildlife, and recreation in and on the water. This designation prohibits any new point source discharges or additional load or increased concentration of specified pollutants.
The Sensitive Water Supplies (SWS) designation applies to public and private water supplies possessing conditions making them more susceptible to pollution events, thus requiring additional protection. This designation restricts point source discharges in the watershed and institutes a 10 μg/L (micrograms per liter) chlorophyll-a criterion to protect against taste and odor problems and reduce water treatment costs.
Outstanding Resource Waters are those constituting outstanding resources or of exceptional recreational and/or ecological significance. This designation prohibits any new point source discharges or additional load or increased concentration of specified pollutants.
Waters designated as Scenic Rivers in Appendix A of the OWQS are protected through restrictions on point source discharges in the watershed. A 0.037 mg/L total phosphorus criterion is applied to all Scenic Rivers in Oklahoma.
Nutrient Limited Watersheds are those containing a waterbody with a designated beneficial use that is adversely affected by excess nutrients.Oklahoma Comprehensive Water Plan Central Regional Report 17
Various types of protection are in place to prevent degradation of groundwater and levels of vulnerability. The Cimarron, North Canadian, and Canadian alluvial aquifers have been identified by the OWRB as highly vulnerable.
Groundwater Protection Areas
Central Region
Groundwater Protection
The Oklahoma Water Quality Standards (OWQS) sets the criteria for protection of groundwater quality as follows:
“If the concentration found in the test sample exceeds [detection limit], or if other substances in the groundwater are found in concentrations greater than those found in background conditions, that groundwater shall be deemed to be polluted and corrective action may be required.”
Wellhead Protection Areas are established by the Oklahoma Department of Environmental Quality (ODEQ) to improve drinking water quality through the protection of groundwater supplies. The primary goal is to minimize the risk of pollution by limiting potential pollution-related activities on land around public water supplies.
Oil and Gas Production Special Requirement Areas, enacted to protect groundwater and/or surface water, can consist of specially lined drilling mud pits (to prevent leaks and spills) or tanks whose contents are removed upon completion of drilling activities; well set-back distances from streams and lakes; restrictions on fluids and chemicals; or other related protective measures.
Nutrient-Vulnerable Groundwater is a designation given to certain hydrogeologic basins that are designated by the OWRB as having high or very high vulnerability to contamination from surface sources of pollution. This designation can impact land application of manure for regulated agriculture facilities.
Appendix H Limited Areas of Groundwater are localized areas where quality is unsuitable for default beneficial uses due to natural conditions or irreversible human-induced pollution. (Not shown on map.)
NOTE: Although the State of Oklahoma has a mature and successful surface water quality monitoring program, no comprehensive approach or plan to monitor the quality of the state’s groundwater resources has been developed.18 Central Regional Report Oklahoma Comprehensive Water Plan
Water Quality Trends Study
As part of the 2012 OCWP Update, OWRB monitoring staff compiled more than ten years of Beneficial Use Monitoring Program (BUMP) data and other resources to initiate an ongoing statewide comprehensive analysis of surface water quality trends. Five parameters were selected for OCWP watershed planning region analysis—chlorophyll-a, conductivity, total nitrogen, total phosphorus, and turbidity.
Reservoir Trends: Water quality trends for reservoirs were analyzed for chlorophyll-a, conductivity, total nitrogen, total phosphorus, and turbidity at sixty-five (65) reservoirs across the state. Data sets were of various lengths, depending on the station’s period of record. The direction and magnitude of trends varies throughout the state and within regions. However, when considered statewide, the final trend analysis revealed several notable details.
Chlorophyll-a and nutrient concentrations continue to increase at a number • of lakes. The proportions of lakes exhibiting a significant upward trend were 42% for chlorophyll-a, 45% for total nitrogen, and 12% for total phosphorus.
Likewise, conductivity and turbidity have trended upward over time. Nearly • 28% of lakes show a significant upward trend in turbidity, while nearly 45% demonstrate a significant upward trend for conductivity.
Stream Trends: Water quality trends for streams were analyzed for conductivity, total nitrogen, total phosphorus, and turbidity at sixty (60) river stations across the state. Data sets were of various lengths, depending on the station’s period of record, but generally, data were divided into historical and recent datasets, and analyzed separately and as a whole. The direction and magnitude of trends varies throughout the state and within regions. However, when considered statewide, the final trend analysis revealed several notable details.
Total nitrogen and phosphorus are very different when comparing period of • record to more recent data. When considering the entire period of record, approximately 80% of stations showed a downward trend in nutrients. However, if only the most recent data (approximately 10 years) are considered, the percentage of stations with a downward trend decreases to 13% for nitrogen and 30% for phosphorus. The drop is accounted for in stations with either significant upward trends or no detectable trend.
Likewise, general turbidity trends have changed over time. Over the entire • period of record, approximately 60% of stations demonstrated a significant upward trend. However, more recently, that proportion has dropped to less than 10%.
Similarly, general conductivity trends have changed over time, albeit less • dramatically. Over the entire period of record, approximately 45% of stations demonstrated a significant upward trend. However, more recently, that proportion has dropped to less than 30%.
Typical Impact of Trends Study Parameters
Chlorophyll-a is a measure of algae growth. When algae growth increases, there is an increased likelihood of taste and odor problems in drinking water as well as aesthetic issues.
Conductivity is a measure of the ability of water to pass electrical current. In water, conductivity is affected by the presence of inorganic dissolved solids, such as chloride, nitrate, sulfate, and phosphate anions (ions that carry a negative charge) or sodium, magnesium, calcium, iron, and aluminum cations (ions that carry a positive charge). Conductivity in streams and rivers is heavily dependent upon regional geology and discharges. High specific conductance indicates high concentrations of dissolved solids, which can affect the suitability of water for domestic, industrial, agricultural and other uses. At higher conductivity levels, drinking water may have an unpleasant taste or odor or may even cause gastrointestinal distress. High concentration may also cause deterioration of plumbing fixtures and appliances. Relatively expensive water treatment processes, such as reverse osmosis, are required to remove excessive dissolved solids from water. Concerning agriculture, most crops cannot survive if the salinity of the water is too high.
Total Nitrogen is a measure of all dissolved and suspended nitrogen in a water sample. It includes kjeldahl nitrogen (ammonia + organic), nitrate and nitrite nitrogen. It is naturally abundant in the environment and is a key element necessary for growth of plants and animals. Excess nitrogen from polluting sources can lead to significant water quality problems, including harmful algal blooms, hypoxia and declines in wildlife and its habitat.
Phosphorus is one of the key elements necessary for growth of plants and animals. Excess nitrogen and phosphorus lead to significant water quality problems, including harmful algal blooms, hypoxia, and declines in wildlife and its habitat. Increases in total phosphorus can lead to excessive growth of algae, which can increase taste and odor problems in drinking water as well as increased costs for treatment.
Turbidity refers to the clarity of water. The greater the amount of total suspended solids (TSS) in the water, the murkier it appears and the higher the measured turbidity. Increases in turbidity can increase treatment costs and have negative effects on aquatic communities by reducing light penetration.Oklahoma Comprehensive Water Plan Central Regional Report 19

Water Demand
The Central Region accounts for about 18% of
the total statewide water demand. Regional
demand will increase by 32% (107,250 AFY)
from 2010 to 2060. Municipal and Industrial
use will continue to be the largest demand
sector.
By 2060, Municipal and Industrial (M&I)
demand is projected to account for
approximately 58% of the Central Region’s
total demand. Currently, 62% of the region’s
M&I demand is supplied by surface water,
12% by alluvial groundwater, and 26% by
bedrock groundwater.
Crop Irrigation demand is expected to account
for 16% of the region’s total 2060 demand.
Currently, 25% of the demand from this
sector is supplied by surface water, 58% by
alluvial groundwater, and 17% by bedrock
groundwater. Predominant irrigated crops in
the Central Region include pasture grasses,
corn, and sod.
Thermoelectric Power demand is projected
to account for 14% of the total 2060 demand.
There are a number of plants using water for
thermoelectric power generation; the three
largest are Oklahoma Gas and Electric Co’s
Seminole plant and McClain Energy Facility
and InterGen North America’s Redbud Power
Plant. Currently, 89% of the demand from this
sector is supplied by surface water, 10%
by alluvial groundwater, and 1% by
bedrock groundwater.
Oil and Gas demand is projected to
account for 5% of the total 2060
demand. Currently, 68% of the
demand from this sector is
supplied by surface water, 12%
by alluvial groundwater, and
20% by bedrock groundwater.
Livestock demand is projected to account for
3% of the total 2060 demand. Currently, 26%
of the demand from this sector is supplied by
surface water, 54% by alluvial groundwater,
and 20% by bedrock groundwater. Livestock
use in the region is predominantly cattle for
cow-calf production, followed by horses, hogs,
and dairy cows.
Self-Supplied Residential demand is also
projected to account for 3% of the total 2060
demand. Currently, 71% of the demand from
this sector is supplied by alluvial groundwater
and 31% by bedrock groundwater.
Self-Supplied Industrial demand is projected
to account for 1% of the total 2060 demand.

Central Region
Water Demand
Water demand refers to the amount of water required to meet the needs of people, communities, industry, agriculture, and other users. Growth in water demand frequently corresponds to growth in population, agriculture, industry, or related economic activity. Demands have been projected from 2010 to 2060 in ten-year increments for seven distinct consumptive water demand sectors.
Water Demand Sectors
nThermoelectric Power: Thermoelectric power producing plants, using both self-supplied water and municipal-supplied water, are included in the thermoelectric power sector.
Self-Supplied Residential: Households on private wells that are not connected to a public water supply system are included in the SSR sector.
nSelf-Supplied Industrial: Demands from large industries that do not directly depend upon a public water supply system. Available water use data and employment counts were included in this sector.
nOil and Gas: Oil and gas drilling and exploration activities, excluding water used at oil and gas refineries (typically categorized as Self-Supplied industrial use), are included in the oil and gas sector.
nMunicipal and Industrial: These demands represent water that is provided by public water systems to homes, businesses, and industries throughout Oklahoma, excluding water supplied to thermoelectric power plants.
nLivestock: Livestock demands were evaluated by livestock group (beef, poultry, etc.) based on the 2007 Agriculture Census.
nCrop Irrigation: Water demands for crop irrigation were estimated using the 2007 Agriculture Census data for irrigated acres by crop type and county. Crop irrigation requirements were obtained primarily from the Natural Resource Conservation Service Irrigation Guide Reports.
OCWP demands were not projected for non-consumptive or instream water uses, such as hydroelectric power generation, fish and wildlife, recreation and instream flow maintenance. Projections, which were augmented through user/stakeholder input, are based on standard methods using data specific to each sector and planning basin.
Projections were initially developed for each county in the state, then allocated to each of the 82 basins. To provide regional context, demands were aggregated by Watershed Planning Region. Water shortages were calculated at the basin level to more accurately determine areas where shortages may occur. Therefore, gaps, depletions, and options are presented in detail in the Basin Summaries and subsequent sections. Future demand projections were developed independent of available supply, water quality, or infrastructure considerations. Impacts of climate change, increased efficiency, conservation, and non-consumptive uses, such as hydropower, are presented in supplemental OCWP reports.
Present and future demands were applied to supply source categories to facilitate an evaluation of potential surface water gaps and aquifer storage depletions at the basin level. For this baseline analysis, the proportion of each supply source used to meet future demands for each sector was held constant at the proportion established through current active water use permit allocations. For example, if the crop irrigation sector in a basin currently uses 80% bedrock groundwater, then 80% of that projected future demand is assumed to use bedrock groundwater. Existing out-of-basin supplies are represented as surface water supplies in the receiving basin and as demand on the source basin.22 Central Regional Report Oklahoma Comprehensive Water Plan
Public Water Providers
There are more than 1,600 Oklahoma water
systems permitted or regulated by the
Oklahoma Department of Environmental
Quality (ODEQ); 785 systems were analyzed
in detail for the 2012 OCWP Update. The
public systems selected for inclusion,
which collectively supply approximately 94
percent of the state’s current population,
consist of municipal or community water
systems and rural water districts that
were readily identifiable as non-profit,
local governmental entities. This and
other information provided in the OCWP
will support provider-level planning by
providing insight into future supply and
infrastructure needs.
The Central Watershed Planning Region
includes 119 of the 785 public supply systems
analyzed for the 2012 OCWP Update. The
Public Water Providers map indicates the
approximate service areas of these systems.
(The map may not accurately represent
existing service areas or legal boundaries. In
addition, water systems often serve multiple
counties and can extend into multiple
planning basins and regions.)
In terms of population served (excluding
provider-to-provider sales), the five largest
systems in the region, in decreasing order,
are Oklahoma City, Norman, Edmond PWA,
Midwest City, and Moore. Together, these
five systems serve more than 71 percent
of the combined OCWP public water
providers’ population in the region.
Demands upon public water systems, which
comprise the majority of the OCWP’s
Municipal and Industrial (M&I) water
demand sector, were analyzed at both the
basin and provider level. Retail demand
projections detailed in the Public Water
Provider Demand Forecast table were
developed for each of the OCWP providers
in the region. These projections include
estimated system
losses, defined as water
lost either during water
production or distribution
to residential homes and
businesses. Retail demands
do not include wholesaled
water.
OCWP provider demand forecasts are
not intended to supersede water demand
forecasts developed by individual providers.
OCWP analyses were made using a consistent
methodology based on accepted data available
on a statewide basis. Where available,
provider-generated forecasts were also
reviewed as part of this effort.

Public Water Provider Demand Forecast (1 of 4)
Central Region
Projections of Retail Water Demands
Each public water supply system has a “retail” demand, defined as the amount of water used by residential and non-residential customers within that provider’s service area. Public-supplied residential demands include water provided to households for domestic uses both inside and outside the home. Non-residential demands include customer uses at office buildings, shopping centers, industrial parks, schools, churches, hotels, and related locations served by a public water supply system. Retail demands do not include wholesale water to other providers.
Municipal and Industrial (M&I) demand is driven by projected population growth and specific customer characteristics. Demand forecasts for each public system are estimated from average water use (in gallons per capita per day) multiplied by projected population. Oklahoma Department of Commerce 2002 population projections (unpublished special tabulation for the OWRB) were calibrated to 2007 Census estimates and used to establish population growth rates for cities, towns, and rural areas through 2060. Population growth rates were applied to 2007 population-served values for each provider to project future years’ service area (retail) populations.
The main source of data for per capita water use for each provider was the 2008 OCWP Provider Survey conducted by the OWRB in cooperation with the Oklahoma Rural Water Association and Oklahoma Municipal League. For each responding provider, data from the survey included population served, annual average daily demand, total water produced, wholesale purchases and sales between providers, and estimated system losses.
For missing or incomplete data, the weighted average per capita demand was used for the provider’s county. In some cases, provider survey data were supplemented with data from the OWRB water rights database. Per capita supplier demands can vary over time due to precipitation and service area characteristics, such as commercial and industrial activity, tourism, or conservation measures. For the baseline demand projections described here, the per capita demand was held constant through each of the future planning year scenarios. OCWP estimates of potential reductions in demand from conservation measures are analyzed on a basin and regional level, but not for individual provider systems.28 Central Regional Report Oklahoma Comprehensive Water Plan

Public Water Provider Demand Forecast (4 of 4)
Central Region
The OWRB provider demand forecasts are not intended to supersede demand forecasts developed by individual water providers. However, the OCWP analyses sought to use a consistent methodology based on accepted data that are available on a statewide basis. When made available, provider-generated forecasts were also reviewed as part of this effort.Oklahoma Comprehensive Water Plan Central Regional Report 31

Wholesale Water Transfers
Some providers sell water on a “wholesale” basis to other providers, effectively increasing the amount of water that the selling provider must deliver and reducing the amount that the purchasing provider diverts from surface and groundwater sources. Wholesale water transfers between public water providers are fairly common and can provide an economical way to meet demands. Wholesale quantities typically vary from year to year depending upon growth, precipitation, emergency conditions, and agreements between systems.
Water transfers between providers can help alleviate costs associated with developing or maintaining infrastructure, such as a reservoir or pipeline; allow access to higher quality or more reliable sources; or provide additional supplies only when required, such as in cases of supply emergencies. Utilizing the 2008 OCWP Provider Survey and OWRB water rights data, the Wholesale Water Transfers table presents a summary of known wholesale arrangements for providers in the region. Transfers can consist of treated or raw water and can occur on a regular basis or only during emergencies. Providers commonly sell to and purchase from multiple water providers. 32 Central Regional Report Oklahoma Comprehensive Water Plan

Public Water Provider Water Rights and Withdrawals - 2010 (1 of 4)
Central Region
Provider Water Rights
Public water providers using surface water or groundwater obtain water rights from the OWRB. Water providers purchasing water from other suppliers or sources are not required to obtain water rights as long as the furnishing entity has the appropriate water right or other source of authority. Each public water provider’s current water right(s) and source of supply have been summarized in this report. The percentage of each provider’s total 2007 water rights from surface water, alluvial groundwater, and bedrock groundwater supplies was also calculated, indicating the relative proportions of sources available to each provider.
A comparison of existing water rights to projected demands can show when additional water rights or other sources and in what amounts might be needed. Forecasts of conditions for the year 2060 indicate where additional water rights may be needed to satisfy demands by that time. However, in most cases, wholesale water transfers to other providers must also be addressed by the selling provider’s water rights. Thus, the amount of water rights required will exceed the retail demand for a selling provider and will be less than the retail demand for a purchasing provider.
In preparing to meet long-term needs, public water providers should consider strategic factors appropriate to their sources of water. For example, public water providers who use surface water can seek and obtain a “schedule of use” as part of their stream water right, which addresses projected growth and consequent increases in stream water use. Such schedules of use can be employed to address increases that are anticipated to occur over many years or even decades, as an alternative to the usual requirement to use the full authorized amount of stream water in a seven-year period. On the other hand, public water providers that utilize groundwater should consider the prospect that it may be necessary to purchase or lease additional land in order to increase their groundwater rights.Oklahoma Comprehensive Water Plan Central Regional Report 35

Provider Supply Plans
In 2008, a survey was sent to 785 municipal and rural water providers throughout Oklahoma to collect vital background water supply and system information. Additional detail for each of these providers was solicited in 2010 as part of follow-up interviews conducted by the ODEQ. The 2010 interviews sought to confirm key details of the earlier survey and document additional details regarding each provider’s water supply infrastructure and plans. This included information on existing sources of supply (including surface water, groundwater, and other providers), short-term supply and infrastructure plans, and long-term supply and infrastructure plans.
In instances where no new source was identified, maintenance of the current source of supply is expected into the future. Providers may or may not have secured the necessary funding to implement their stated plans concerning infrastructure needs, commonly including additional wells or raw water conveyance, storage, and replacement/upgrade of treatment and distribution systems.
Additional support for individual water providers wishing to pursue enhanced planning efforts is documented in the Public Water Supply Planning Guide. This guide details how information contained in the OCWP Watershed Planning Region Reports and related planning documents can be used to formulate provider-level plans to meet present and future needs of individual water systems. 38 Central Regional Report Oklahoma Comprehensive Water Plan

Central Regional Report 1
Oklahoma Comprehensive Water Planavailability and potential shortages are documented in the OCWP Physical Water Supply Availability Report. Statewide water demand projection methods and results are presented in the Water Demand Forecast Report. Permitting availability was evaluated based on the OWRB’s administrative protocol and documented in the Water Supply Permit Availability Report. All supporting documentation can be found on the OWRB’s website.federal agency staff, industry representatives, and stakeholder groups for each demand sector. Surface water supply data for each of the 82 basins used 58 years of publicly-available daily streamflow gage data collected by the USGS. Groundwater resources were characterized using previously-developed assessments of groundwater aquifer storage and recharge rates.
Additional information gained during the development of the 2012 Update is provided in various OCWP supplemental reports. Assessments of statewide physical water
The Oklahoma Comprehensive Water Plan (OCWP) was originally developed in 1980 and last updated in 1995. With the specific objective of establishing a reliable supply of water for state users throughout at least the next 50 years, the current update represents the most ambitious and intensive water planning effort ever undertaken by the state. The 2012 OCWP Update is guided by two ultimate goals:
Provide safe and dependable water supply 1. for all Oklahomans while improving the economy and protecting the environment.
Provide information so that water 2. providers, policy makers, and water users can make informed decisions concerning the use and management of Oklahoma’s water resources.
In accordance with the goals, the 2012 OCWP Update has been developed under an innovative parallel-path approach: inclusive and dynamic public participation to build sound water policy complemented by detailed technical evaluations.
Also unique to this update are studies conducted according to specific geographic boundaries (watersheds) rather than political boundaries (counties). This new strategy involved subdividing the state into 82 surface water basins for water supply availability analysis (see the OCWP Physical Water Supply Availability Report). Existing watershed boundaries were revised to include a United States Geological Survey (USGS) stream gage at or near the basin outlet (downstream boundary), where practical. To facilitate consideration of regional supply challenges and potential solutions, basins were aggregated into 13 distinct Watershed Planning Regions.
This Watershed Planning Region Report, one of 13 such documents prepared for the 2012 OCWP Update, presents elements of technical studies pertinent to the Central Region. Each regional report presents information from both a regional and multiple basin perspective, including water supply/demand analysis results, forecasted water supply shortages, potential supply solutions and alternatives, and supporting technical information.
Integral to the development of these reports was the Oklahoma H2O model, a sophisticated database and geographic information system (GIS) based analysis tool created to compare projected water demand to physical supplies in each of the 82 OCWP basins statewide. Recognizing that water planning is not a static process but rather a dynamic one, this versatile tool can be updated over time as new supply and demand data become available, and can be used to evaluate a variety of “what-if” scenarios at the basin level, such as a change in supply sources, demand, new reservoirs, and various other policy management scenarios.
Primary inputs to the model include demand projections for each decade through 2060, founded on widely-accepted methods and peer review of inputs and results by state and
Introduction
The primary factors in the determination of reliable future water supplies are physical supplies, water rights, water quality, and infrastructure. Gaps and depletions occur when demand exceeds supply, and can be attributed to physical supply, water rights, infrastructure, or water quality constraints.
As a key foundation of OCWP technical work, a computer-based analysis tool, “Oklahoma H2O,” was created to compare projected demands with physical supplies for each basin to identify areas of potential water shortages.
Regional Overview
The Central Watershed Planning Region includes nine basins (for reference, numbered 50, 51, 56-58, 60-62, and 64). The region is located in the Central Lowland physiography province, encompassing 10,142 square miles in central Oklahoma, spanning from southern Woods County to Hughes and Pontotoc Counties in the southeastern portion of the region and including all or portions of Alfalfa, Woodward, Garfield, Major, Kingfisher, Logan, Blaine, Dewey, Creek, Lincoln, Okmulgee, Canadian, Oklahoma, Okfuskee, Caddo, Seminole, Pottawatomie, Grady, Cleveland, McClain, and Garvin Counties.
The region displays many of the physical diversities of the state. The extremes range from the metropolitan areas of Oklahoma City in Oklahoma County to the more forested areas of the southeast, the open farmland in the central and western areas, and the sand hills in the western portion of the region.
The region’s climate is moist and sub-humid with the mean annual temperature ranging from 59° F to 62° F. Annual average precipitation ranges from 26 inches in the northwest to 46 inches in the southeastern corner. Annual lake evaporation ranges from 50 to 62 inches and exceeds precipitation. Frequent droughts cause severe crop damage while severe flooding also occurs as the result of concentrated areas of heavy precipitation. Thunderstorms accompanied by high winds, hail, and heavy rain increase the likelihood of flash flooding, emphasizing the necessity of watershed protection and flood prevention projects.
The largest cities in the region include Oklahoma City (2010 population of 501,450), Norman (109,865), Edmond (79,562), Midwest City (56,886), and Moore (52,621). The greatest demand is from Municipal and Industrial water use.
By 2060, this region is projected to have a total demand of 442,890 acre-feet per year (AFY), an increase of approximately 107,250 AFY (32%) from 2010.2 Central Regional Report
Oklahoma Comprehensive Water Planand their tributaries to provide public water supply, flood control, and recreation. There are two major federal reservoirs in the Central Region: Arcadia, built by the U.S. Army Corps of Engineers and Thunderbird, constructed by the Bureau of Reclamation. Large municipal water supply lakes in the region include Oklahoma City’s three area lakes—Overholser, Stanley Draper, and Hefner. There are 16 additional significant lakes in the region with normal storage ranging from 709 AF (El Reno Lake) to 23,000 AF (Lake Konawa). Surface water in Basins 50 and 51 is fully allocated, limiting diversions to existing permitted amounts. All other basins in the region are expected to have available surface water for new permits to meet local demand through 2060. Surface water quality in the region is variable and considered poor in several basins relative to other basins in the state. Multiple rivers, creeks, and reservoirs
The Central Region accounts for 18% of the state’s total water demand. The largest demand sectors are Municipal and Industrial (58% of the region’s overall 2010 demand), Crop Irrigation (16%), and Thermoelectric Power (14%).
Water Resources & Limitations
Surface Water
Surface water supplies, including reservoirs, are used to meet 56% of the Central Region’s demand. Surface water supply shortages are expected by 2020 in all basins in the region, except Basins 60 and 62. Shortages are expected to have a moderate to high probability of occurring. The region is supplied by five major rivers: the Canadian, Cimarron, Little, Deep Fork, and North Canadian. Large reservoirs have been built on these rivers
Central Regional Summary in the region are impaired for Public and Private Water Supply use and Agricultural use due to high levels of oil and grease, chloride, total dissolved solids (TDS), and chlorophyll a.
Alluvial Groundwater
Alluvial groundwater is used to meet 23% of the demand in the region. The majority of currently permitted groundwater withdrawals in the region are from the Cimarron River, Canadian River, and North Canadian River alluvial aquifers. Each has more than 2.7 million AF of storage in the region. There are also substantial water rights in the Gerty Sand alluvial aquifer and multiple minor aquifers. If alluvial groundwater continues to supply a similar portion of demand in the future, storage depletions from these aquifers may occur throughout the year. The largest storage depletions are projected to occur in the summer. The availability of permits is not expected to constrain the use of alluvial groundwater supplies to meet local demand through 2060.
Synopsis
The Central Watershed Planning Region relies primarily on surface water supplies (including reservoirs), out-of-basin supplies, and to a lesser extent alluvial and bedrock groundwater.
It is anticipated that water users in the region will continue to rely on these sources to meet future demand.
By 2020, surface water supplies may be insufficient at times to meet demand in all basins in the region, except Basins 60 and 62.
By 2020, alluvial and bedrock groundwater storage depletions may occur and eventually lead to higher pumping costs, the need for deeper wells, and potential changes to well yields or water quality.
To reduce the risk of adverse impacts on water supplies, it is recommended that gaps and storage depletions be decreased where economically feasible.
Additional conservation could reduce surface water gaps and groundwater storage depletions, eliminating bedrock groundwater depletions in Basin 50 and alluvial groundwater storage depletions in Basins 50 and 62.
Aquifer storage and recovery in Basins 50 and 51 could be considered to store variable surface water supplies, increase groundwater storage, and reduce adverse effects of localized storage depletions.
Surface water alternatives, such as groundwater sources, out-of-basin supplies, and/or developing new reservoirs, could mitigate gaps without major impacts to groundwater storage.

Bedrock Groundwater
Bedrock groundwater is used to meet 21% of the demand in the region. The majority of currently permitted bedrock groundwater withdrawals in the region are from the Garber-Wellington aquifer. This aquifer has more than 55.6 million AF of storage in the Central Region. There are also substantial water rights in multiple major and minor aquifers. Recharge to major aquifers is expected to be sufficient to meet some of the region’s bedrock groundwater demand through 2060. Bedrock groundwater storage depletions may occur in Basins 50, 51, 57, and 64, typically by 2020. The availability of permits is not expected to constrain the use of bedrock groundwater supplies to meet local demand through 2060. However, an ongoing multi-year study of the Garber-Wellington may result in a change to the 2 AFY/acre share currently allowed under temporary permit.
Water Supply Limitations
Surface water limitations were based on physical availability, water supply availability for new permits, and water quality. Groundwater limitations were based on the total size and rate of storage depletions in major aquifers. Groundwater permits are not expected to constrain the use of groundwater through 2060, and insufficient statewide groundwater quality data are available to compare basins based on groundwater quality. Basins with the most significant water supply challenges statewide are indicated by a red box. The remaining basins with surface water gaps or groundwater storage depletions were considered to have potential limitations (yellow). Basins without gaps and storage depletions were considered to have minimal limitations (green). Detailed explanations of each basin’s supplies are provided in individual basin summaries and supporting data and analysis.4 Central Regional Report Oklahoma Comprehensive Water Plan
Water Supply Options
To quantify physical surface water gaps and groundwater storage depletions through 2060, use of existing out-of-basin and local supplies was assumed to continue in current (2010) proportions. Surface water supplies, reservoirs, out-of-basin supplies, and bedrock groundwater supplies are expected to continue to supply the majority of demand in the Central Region. Surface water users may have physical surface water supply shortages (gaps) in the future, except in Basins 60 and 62. Alluvial groundwater storage depletions of major and minor aquifers are also projected in the future and may occur in most basins in the region by 2020. Bedrock groundwater storage depletions may occur in Basins 50, 51, 57, and 64. The development of additional alluvial and bedrock groundwater supplies could be an effective a long-term water supply option, except in portions of the North Canadian River alluvial aquifer.
Water conservation could aid in reducing projected gaps and groundwater storage depletions or delaying the need for additional infrastructure. Moderately expanded conservation activities could reduce gaps and storage depletions throughout the region, and could eliminate bedrock groundwater storage depletions in Basin 50 and alluvial groundwater storage depletions in Basin 62. Future reductions could occur from substantially expanded conservation activities. These measures would require a shift from crops with high water demand (e.g., corn for grain and forage crops) to low water demand crops (e.g., sorghum for grain or wheat for grain) along with increased efficiency and increased public water supplier conservation. In basins with lower frequencies of shortages, temporary drought management measures may be an effective water supply option.
New reservoirs and expanded use of existing reservoirs could enhance the dependability of surface water supplies and reduce gaps in some basins in the region. Several small municipal reservoirs may have unpermitted yield available for new users; however, these supplies are small compared to the demand in the region. Oklahoma City currently receives substantial supplies from the Blue-Boggy Watershed Planning Region via the Atoka pipeline. The City of Ada also receives out-of-basin supplies from Byrds Mill Spring and the Arbuckle-Simpson aquifer in the Blue-Boggy Region. These out-of-basin supplies are expected to continue to provide water to the region in the future. The OCWP Reservoir Viability Study, which evaluated the potential for reservoirs throughout the state, identified 16 potentially viable sites in the Central Region. These water sources could serve as in-basin storage or out-of-basin supplies to provide additional supplies to reduce the region’s and surrounding regions’ surface water gaps and groundwater storage depletions. However, due to the distance of these potential reservoirs to demand points in each basin, this water supply option may not be cost-effective for many users.
The projected growth in surface water use could instead be supplied in part by increased use of the Garber-Wellington aquifer, Canadian River aquifer, Cimarron River aquifer or the North Canadian River aquifer, which would result in small or minimal increases in projected groundwater storage depletions. However, these aquifers do not underlie the entire region and water quality may limit their use. Also, ongoing studies to determine the maximum annual yield and equal proportionate share for the Garber-Wellington aquifer may change the current amount (2 AFY/acre) of water allowed under temporary permits.
Effectiveness of water supply options in each basin in the Central Region. This evaluation was based upon results of physical water supply availability analysis, existing infrastructure, and other basin-specific factors.

The mainstem of the Cimarron River runs for 150 miles through Basin 64. Major tributaries include Turkey Creek (70 miles long) and Cottonwood Creek (60 miles long). Water quality is degraded by naturally occurring salt sources in the upper reaches near the Harper/Woods County line.
Water Supply
Physical Water Availability
Surface Water Resources
Surface water supply has historically been used to meet just over half of the demand in the Central Region. The region’s major rivers include the Canadian, Cimarron, Little, Deep Fork, and North Canadian. Many streams in this region experience a wide range of flows, including both periodic no-flow conditions and flooding events.
The North Canadian River (320 miles long in the Central Region) flows from the Panhandle Region through Basins 50 and 51 in the Central Region. Total dissolved solids (TDS) and chloride levels are relatively high and Oklahoma City wastewater return flows constitute a large percentage of the North Canadian River’s total flow.
The Deep Fork River originates in the Central Region and is 140 miles long in Basin 60. The river is generally of fair quality with moderate mineral content. However, the chloride content may reach high levels during certain periods of the year.
The Canadian River (190 miles long in the Central Region) enters the Central Region from the West Central Region. Major tributaries in the region include Walnut Creek (25 miles long), the Little River (110 miles long), and Salt Creek
As important sources of surface water in Oklahoma, reservoirs and lakes help provide dependable water supply storage, especially when streams and rivers experience periods of low seasonal flow or drought.Oklahoma Comprehensive Water Plan Central Regional Report 7
In the Central Region, streamflow is generally
intermittent. Existing reservoirs in the region
increase the dependability of surface water
supply for many public water systems and other
users. Some reservoirs provide terminal storage
for out-of-basin supplies. There are two major
federal reservoirs in the region. Lake Arcadia
in Basin 60 was completed in 1986 on the Deep
Fork River by the U.S. Army Corps of Engineers
for water supply, recreation, and fish and
wildlife purposes. The lake provides 12,320 AFY
of dependable yield, which is allocated to the
City of Edmond. Lake Thunderbird in Basin 62
was built in 1965 on the Little River by the U.S.
Bureau of Reclamation. Project purposes include
flood control, water supply, recreation, and fish
and wildlife. Most of Thunderbird’s water supply
yield is allocated to the Central Oklahoma Master
Conservancy District, which supplies municipal
and industrial water to its member cities
(Norman, Midwest City and Del City).
There are five major municipal lakes in the
Central Region. Three were constructed by
the City of Oklahoma City, one by the City
of Shawnee, and the fifth by the NRCS and
is operated by the Pottawatomie County
Development Authority. Lake Stanley Draper, in
Basin 62, was constructed in 1962 by Oklahoma
City and is located on East Elm Creek. The
impoundment is used primary as terminal storage
for water conveyed from Atoka Lake and McGee
Creek in the Blue-Boggy Watershed Planning
Region via the 90 mgd Atoka Pipeline. While
Lake Stanley Draper has little dependable yield
of its own, it can provide a dependable yield of
about 86,000 AFY comprised of deliveries from
Atoka and McGee Creek minus losses.
Oklahoma City’s other two lakes in the Central
Region, Lake Overholser in Basin 51 and Lake
Hefner in Basin 64, are operated to utilize the
City’s water right allocations from Canton Lake
in the Panhandle Watershed Planning Region
and the North Canadian River. Lake Overholser
was built in 1919 on the North Canadian River
for the purposes of water supply and recreation.
The lake has a dependable yield of 5,000 AFY,
which is supplemented by releases from Canton
Lake via the North Canadian River. Lake Hefner
was constructed on Bluff
Creek in 1943 by Oklahoma
City for the purposes of
offstream water supply
storage and recreation.
The lake serves as terminal
storage for diversions from
the North Canadian
River and releases
from Canton
Lake via a canal
that diverts water
from the river near
Lake Overholser. The system
provides a dependable yield of 80,000
AFY to Oklahoma City and is fully
allocated.
Shawnee Twin Lakes were
constructed by the City of Shawnee
on South Deer Creek in Basin 50. These
two lakes, one constructed in 1935 and one
in 1960, are connected by a canal and have
a combined yield of 4,400 AFY that is fully
allocated to the City of Shawnee. Wes Watkins
Reservoir, also in Basin 50, was constructed
in 1997 by the NRCS for the purposes of flood
control, water supply and recreation. The
lake is operated by the Pottawatomie County
Development Authority.
Some of the other significant lakes in the region
include: Lake Wetumka and Tecumseh Lake in
Basin 50; El Reno Lake in Basin 51; Konawa and
Holdenville Lakes in Basin 56; Purcell Lake in
Basin 57; Bell Cow, Meeker, Prague City, Stroud,
Chandler, and Okemah Lakes in Basin 60; and
Guthrie and Liberty Lakes in Basin 64.
There are many other small Natural Resources
Conservation Service (NRCS), municipal and
privately owned lakes in the region that provide
water for public water supply, agricultural water
supply, watershed protection, flood control and
recreation.
Surface Water Resources
Central Region
Major reservoirs in the Central Region include Arcadia, Thunderbird, Overholser, Hefner,
Shawnee Twin Lakes, Wes Watkins, and Stanley Draper. These lakes may serve multiple
purposes, such as water supply, irrigation, recreation, hydropower generation, and flood
control. Reservoirs designed for multiple purposes typically possess a specific volume of water
storage assigned for each purpose.

Annual streamflow in 2060 was estimated using historical gaged flow and projections of increased surface water use from 2010 to 2060.
Surface Water Flows (1950-2007)
Central Region
Surface water sources supply about half of the demand in the Central Region. Surface water gaps can occur due to seasonal, long-term hydrologic (drought), or localized variability in surface water flows. Several large reservoirs have been constructed to reduce the impacts of drier periods on surface water users.
Water Supply Availability Analysis
For OCWP physical water supply availability analysis, water supplies were divided into three categories: surface water, alluvial aquifers, and bedrock aquifers. Physically available surface water refers to water currently in streams, rivers, lakes, and reservoirs.
The range of historical surface water availability, including droughts, is well-represented in the Oklahoma H2O tool by 58 years of monthly streamflow data (1950 to 2007) recorded by the U.S. Geological Survey (USGS). Therefore, measured streamflow, which reflects current natural and human created conditions (runoff, diversions and use of water, and impoundments and reservoirs), is used to represent the physical water that may be available to meet projected demand.
The estimated average and minimum annual streamflow in 2060 were determined based on historic surface water flow measurements and projected baseline 2060 demand (see Water Demand section). The amount of streamflow in 2060 may vary from basin-level values, due to local variations in demands and local availability of supply sources. The estimated surface water supplies include changes in historical streamflow due to increased upstream demand, return flows, and increases in out-of-basin supplies from existing infrastructure. Permitting, water quality, infrastructure, non-consumptive demand, and potential climate change implications are considered in separate OCWP analyses. Past reservoir operations are reflected and accounted for in the measured historical streamflow downstream of a reservoir. For this analysis, streamflow was adjusted to reflect interstate compact provisions in accordance with existing administrative protocol.
The amount of water a reservoir can provide from storage is referred to as its yield. The yield is considered the maximum amount of water a reservoir can dependably supply during critical drought periods. OCWP physical availability analyses considered the unused yield of existing reservoirs. Future potential reservoir storage was considered as a water supply option.
Groundwater supplies are quantified by the amount of water that the aquifer holds (“stored” water) and the rate of aquifer recharge. In Oklahoma, recharge to aquifers is generally from precipitation that falls on the aquifer and percolates to the water table. In some cases, where the altitude of the water table is below the altitude of the stream-water surface, surface water can seep into the aquifer.
For this analysis, alluvial aquifers are defined as aquifers comprised of river alluvium and terrace deposits, occurring along rivers and streams and consisting of unconsolidated deposits of sand, silt, and clay. Alluvial aquifers are generally thinner (less than 200 feet thick) than bedrock aquifers, feature shallow water tables, and are exposed at the land surface, where precipitation can readily percolate to the water table. Alluvial aquifers are considered to be more hydrologically connected with streams than are bedrock aquifers and are therefore treated separately.
Bedrock aquifers consist of consolidated (solid) or partially consolidated rocks, such as sandstone, limestone, dolomite, and gypsum. Most bedrock aquifers in Oklahoma are exposed at land surface, either entirely or in part. Recharge from precipitation is limited in areas where bedrock aquifers are not exposed.
For both alluvial and bedrock aquifers, this analysis was used to predict potential groundwater depletions based on the difference between the groundwater demand and recharge rate. While potential storage depletions do not affect the permit availability of water, it is important to understand the extent of these depletions.Central Regional Oklahoma Comprehensive Water Plan Report 9
downward to sandy clay, sand, and fine gravel, Maximum thickness reaches 80 feet with well yields ranging between 100 and 200 gpm in the alluvium and 100 and 500 gpm in the terrace deposits. The terrace deposits are overlain by sand dunes. The water is very hard and is classified as calcium magnesium bicarbonate type. Extensive pumping can make this formation susceptible to salt water intrusion.
The Canadian River alluvial aquifer underlies portions of Basins 51, 56, 57, 58, 61, and 62. The formation consists of clay and silt downgrading to fine- to coarse-grained sand with lenses of basal gravel. Formation thicknesses range from 20 to 40 feet in the alluvium with a maximum of 50 feet in the terrace deposits. Yields in the alluvium range between 100 and 400 gpm and between 50 and 100 gpm in the terrace. Although the water is a very hard calcium bicarbonate type with TDS concentrations of approximately 1,000 mg/L, it is generally suitable for most municipal and industrial uses.
The North Canadian River alluvial aquifer underlies portions of Basins 50, 51, and 64.The formation consists of fine- to coarse-grained sand with minor clay and silt and local lenses of basal gravel overlain by dune sand. Formation thickness averages 30 feet in the alluvium with a maximum of 300 feet in the terrace deposits. Yields range between 300 and 600 gpm in the alluvium and 100 to 300 gpm in the terrace formations. The water is a very hard calcium bicarbonate type with TDS concentrations of up to 1,000 mg/L.
The Cimarron River alluvial aquifer underlies a portion of Basin 64. The formation tends to consist of silt and clay deposits changing
Groundwater Resources
Three major bedrock aquifers underlie the Central Watershed Planning Region: Rush Springs, Garber-Wellington, and Vamoosa-Ada. Five major alluvial aquifers underlie the region: Canadian River, Cimarron River, Enid Isolated Terrace, Gerty Sand, and North Canadian River.
The Garber-Wellington aquifer underlies portions of Basins 50, 51, 56, 58, 60, 61, 62, and 64. The formation consists of fine-grained sandstone interbedded with siltstone and shale. Depth to water varies from less than 100 feet to 250 feet; saturated thickness ranges from 150 to 650 feet. Wells generally yield from 200 to 400 gpm. Water quality is generally good, but in some areas, concentrations of nitrate, arsenic, chromium, and selenium may exceed drinking water standards.
The Vamoosa-Ada aquifer underlies portions of Basins 50, 56, 60, 61, and 62. The formation consists of 125 to 1,000 feet of interbedded sandstone, shale, and conglomerate. Wells commonly yield 25 to 150 gpm. Water quality is generally good and suitable for use as public supply, although iron infiltration and hardness are problems in some areas and there are local problems due to contamination resulting from past oil and gas activities.
The Rush Springs aquifer underlies a portion of Basin 58. The formation consists of a fine-grained sandstone aquifer with some shale, dolomite, and gypsum. Thickness of the aquifer ranges from 200 to 300 feet. Wells commonly yield 25 to 400 gpm. The water tends to be very hard, requiring water softening to address aesthetic issues for public water supply use. In some areas nitrate and sulfate concentrations exceed drinking water standards, limiting its use for drinking water.
Withdrawing groundwater in quantities exceeding the amount of recharge to the aquifer may result in reduced aquifer storage. Therefore, both storage and recharge were considered in determining groundwater availability.
Areas without delineated aquifers may have groundwater present. However, specific quantities, yields, and water quality in these areas are currently unknown.

1 Bedrock aquifers with typical yields greater than 50 gpm and alluvial aquifers with typical yields greater than 150 gpm are considered major.
Permits to withdraw groundwater from aquifers (groundwater basins) where the maximum annual yield has not been set are “temporary” permits that allocate 2 AFY/acre. The temporary permit allocation is not based on storage, discharge or recharge amounts, but on a legislative (statute) estimate of maximum needs of most landowners to ensure sufficient availability of groundwater in advance of completed and approved aquifer studies. As a result, the estimated amount of Groundwater Available for New Permits may exceed the estimated aquifer storage amount. For aquifers (groundwater basins) where the maximum annual yield has been determined (with initial storage volumes estimated), updated estimates of amounts in storage were calculated based on actual reported use of groundwater instead of simulated usage from all lands.10 Central Regional Report Oklahoma Comprehensive Water Plan
Groundwater Resources
Central Region
The Gerty Sand alluvial aquifer underlies a portion of Basin 56. The formation consists of gravel, sand, silt, clay, and volcanic ash. The saturated thickness varies from 5 to 75 feet, averaging 28 feet. Depth to water ranges from 10 to 110 feet. Typical well yields vary from 100 to 450 gpm with some wells yielding as much as 850 gpm. Water quality is fair to good and moderately hard with TDS values usually less than 1,000 mg/L.
The Enid Isolated Terrace alluvial aquifer underlies a small portion of Basin 64. The formation is composed of terrace deposits that consist of discontinuous layers of clay, sandy clay, sand, and gravel.
Minor bedrock aquifers in the region include the East-Central Oklahoma, El Reno, and North-Central Oklahoma aquifers. Minor alluvial aquifers include the Fairview Isolated Terrace, Isabella Isolated Terrace, and Loyal Isolated Terrace. Minor aquifers may have a significant amount of water in storage and high recharge rates, but generally low yields of less than 50 gpm per well. Groundwater from minor aquifers is an important source for domestic and stock water use for individuals in outlying areas not served by rural water systems, but yields might be insufficient for high volume users.Oklahoma Comprehensive Water Plan Central Regional Report 11
Surface Water Permit Availability
Central Region
There is no surface water available for new permits in Basins 50 and 51, but projections indicate that there will be surface water available for new permits through 2060 in all other basins in the Central Region.
Projections indicate that the use of groundwater to meet in-basin demand is not expected to be limited by the availability of permits through 2060 in the Central Region.
Groundwater Permit Availability
Central Region
Permit Availability
For the OCWP water availability analysis, “permit availability” pertains to the amount of water that could be made available for withdrawals under permits issued in accordance with Oklahoma water law.
Projections indicate that there will be no surface water available for new permits in Basins 50 and 51, but surface water will be available for new permits through 2060 in all other basins in the Central Region. For groundwater, equal proportionate shares in the Central Region range from 0.5 acre-feet per year (AFY) per acre to 2 AFY per acre.
If water authorized by a stream water right is not put to beneficial use within the specified time, the OWRB may reduce or cancel the unused amount and return the water to the public domain for appropriation to others.
Water Use Permitting in Oklahoma
Oklahoma stream water laws are based on riparian and prior appropriation doctrines. Riparian rights to a reasonable use of water, in addition to domestic use, are not subject to permitting or oversight by the OWRB. An appropriative right to stream water is based on the prior appropriation doctrine, which is often described as “first in time, first in right.” If a water shortage occurs, the diverter with the older appropriative water right will have first right among other appropriative right holders to divert the available water up to the authorized amount.
The permit availability of surface water is based on the average annual flow in the basin, the amount of water that flows past the proposed diversion point, and existing water uses upstream and downstream in the basin. The permit availability of surface water at the outlet of each basin in the region was estimated through OCWP technical analyses. The current allocated use for each basin is also noted to give an indication of the portion of the average annual streamflow used by existing water right holders. A site-specific analysis is conducted before issuing a permit.
Groundwater permit availability is generally based on the amount of land owned or leased that overlies a specific aquifer (groundwater basin). State law provides for the OWRB to conduct hydrologic investigations of groundwater basins and to determine amounts of water that may be withdrawn. After a hydrologic investigation has been conducted on a groundwater basin, the OWRB determines the maximum annual yield of the basin. Based on the “equal proportionate share”—defined as the portion of the maximum annual yield of water from a groundwater basin that is allocated to each acre of land overlying the basin—regular permits are issued to holders of existing temporary permits and to new permit applicants. Equal proportionate shares have yet to be determined on many aquifers in the state. For those aquifers, “temporary” permits are granted to users allocating two acre-feet of water per acre of land per year. When the equal proportionate share and maximum annual yield are approved by the OWRB, all temporary permits overlying the studied basin are converted to regular permits at the new approved allocation rate. As with stream water, a groundwater permit grants only the right to withdraw water; it does not ensure yield.12 Central Regional Report Oklahoma Comprehensive Water Plan
Water Quality
Water quality of the Central Watershed Planning
Region is defined by numerous minor and major
water supply reservoirs and the middle Cimarron
and lower Canadian River watersheds. The area
is co-dominated by two ecoregions, the Central
Great Plains (CGP) to the west and the Cross
Timbers (CT) to the east. Several additional
ecoregions intersect the periphery of the planning
region, but their impact is minimal and they will
not be addressed in this discussion.
The western half of the planning region is
characterized by the Prairie Tablelands and
several other intervening CGP ecoregions, the
Pleistocene Sand Dunes/Sandsage Grassland,
and Gypsum Hills. The Cimarron and North
Canadian Rivers drain the area from northwest
to southeast, and the Canadian River intersects
the area in the south. The Prairie Tablelands are
nearly level, underlain by shale, sandstone, and
siltstone. They are dominated by cropland with
dense mixed grass prairies. Streams are typically
turbid and silt-dominated with some sand,
lying in broad, shallow, low gradient channels
with highly incised banks. The tributaries of
the major rivers best exemplify water quality
in the tablelands. These include Buggy Creek
along the Canadian, and from west to east on the
Cimarron, Eagle Chief, Turkey, Kingfisher, and
Cottonwood Creeks. Salinity is high throughout
the watersheds. Mean conductivities range from
1,029 μS/cm on Cottonwood Creek to near 2,300
μS/cm on Kingfisher Creek, while Buggy Creek
is 1,100 μS/cm. Nutrient concentrations are also
high. Mean concentrations of total phosphorus
(TP) and total nitrogen (TN) range from 0.18
and 2.05 ppm on Kingfisher Creek to 0.98 and
4.08 ppm on Cottonwood Creek. Buggy Creek
is similar with mean TP and TN of 0.38 and 2.0
ppm. Water clarity is poor to very poor, with
mean turbidity ranging from 65 NTU
on Eagle Chief Creek to 184 NTU on
Cottonwood Creek; Buggy Creek
is 160 NTU. Ecological diversity
is average and highly impacted by
siltation/sedimentation, habitat
degradation, and channelization.
Conversely, the Pleistocene
Sand Dunes have more
permeable sandy soils interlaced
with springs and inter-dune
wetlands. Streams have incised,
highly erodible banks but are
typically sandy. The northern and
eastern banks of the major river
systems are influenced heavily by
the features and are typically sandier
than many of their tributaries. The
Cimarron and North Canadian best
exemplify the area, as well as El
Reno Lake in the North Canadian
watershed. Salinity on the Cimarron
is very high and steadily decreases
from west to east. Near Waynoka,
mean conductivity is nearly 29,000
μS/cm, but at Guthrie, it decreases
to 8,730 μS/cm. Salinity on the
North Canadian (including El
Reno Lake) and Canadian is much
lower with mean conductivities
of 1,350-1,400 μS/cm. Nutrient
concentrations increase steadily
along the Cimarron. Near Waynoka,
the river is mesotrophic, with low
TP and TN mean concentrations
of 0.05 and 0.69 ppm. The river
gradually becomes eutrophic to
hyper-eutrophic; at Guthrie, TP and
TN increase to 0.36 and 1.95 ppm.
The North Canadian and Canadian
are also hyper-eutrophic, with TP ranging from
0.20-0.22 ppm and TN from 0.99-1.24 ppm. El
Reno Lake is hyper-eutrophic and nitrogen-limited.
Water clarity is excellent to average on
the Cimarron with mean turbidity values of 6
Lake Trophic Status
A lake’s trophic state, essentially a measure of its
biological productivity, is a major determinant of
water quality.
Oligotrophic: Low primary productivity and/or low
nutrient levels.
Mesotrophic: Moderate primary productivity with
moderate nutrient levels.
Eutrophic: High primary productivity and nutrient
rich.
Hypereutrophic: Excessive primary productivity
and excessive nutrients.
The Central Planning Region is a transitional area between the Central Great Plains and
Cross Timbers. Water quality is highly influenced by both geology and land use practices,
and is generally poor to good depending on drainage and location.
Ecoregions

Oklahoma Comprehensive Water Plan Central Regional Report 13
NTU near Waynoka and 33 NTU near Guthrie.
The North Canadian has good clarity (18 NTU)
while the Canadian is average (40 NTU). El
Reno Lake has poor clarity. Ecological diversity
is good in the Canadian watersheds but can be
impacted by habitat degradation, channelization,
and sedimentation. Conversely, diversity in the
Cimarron is low and is naturally impacted by
higher than normal salinity and also by flow
modification and sedimentation.
The Gypsum Hills are characterized by
breaks, escarpments, gorges, ledges, caves,
and canyons. Geological features were
formed by the differential erosion of
underlying gypsum, shale, dolomite,
fine sand, and rock salt. The features
create flora and fauna that are unique
within the CGP. The area is covered by
mixed grass prairie and intermittent tree groves.
Streams are typically bedrock/gravel/cobble,
with habitat that is typically more diverse than
surrounding areas. Griever Creek has relatively
high salinity (mean conductivity = 2,870
μS/cm), and poor water clarity (58 NTU).
However, nutrient concentrations are low
with mean TP of 0.11 and TN of 0.70 ppm.
The Northern Cross Timbers extends from
roughly the center of the Oklahoma City
metropolitan area south to Purcell and
east through the remainder of the region.
The Northern Timbers is densely forested
and covered by a variety of flora including
oak savanna, scrub oak forest, eastern
red cedar, and intervening grasslands.
Land use is mixed with rangeland,
cropland, urban, and intense oil/natural
gas production, which has led to higher
than normal salinity in some watersheds.
Streams are typically contained in shallow,
sandy channels and are normally moderately
to heavily incised. However, deep pools, riffles,
and rocky substrates exist in various parts
of the area. Ecological diversity is mixed and
can be affected by habitat degradation, flow
modification, channelization, and sedimentation/
siltation. The area is best exemplified by the
lower North Canadian and Canadian River
watersheds, including the Deep Fork of the
Water Quality Standards Implementation
Central Region
BUMP monitoring sites and streams with TMDL studies completed or underway. The
Oklahoma Conservation Commission has begun a watershed implementation project on
Lake Thunderbird to address non-point source runoff through low-impact development. The
Oklahoma Department of Environmental Quality has completed TMDL studies on North
Canadian River, Turkey Creek, and Little Turkey Creek. Several other TMDL studies are
underway or scheduled.
Water Quality Standards and
Implementation
The Oklahoma Water Quality Standards
(OWQS) are the cornerstone of the
state’s water quality management
programs. They are a set of rules
promulgated under the federal Clean
Water Act and state statutes to maintain
and protect the quality of state waters.
The OWQS designate beneficial uses
for streams, lakes and other bodies of
surface water, and for groundwater
that has a mean concentration of Total
Dissolved Solids of 10,000 milligrams
per liter or less. Beneficial uses are the
activities for which a waterbody can
be used based on physical, chemical,
and biological characteristics as well as
geographic setting, scenic quality, and
economic considerations. Beneficial
uses include such categories as Fish and
Wildlife Propagation, Public and Private
Water Supply, Primary (or Secondary)
Body Contact Recreation, Agriculture,
and Aesthetics. The OWQS also contain
standards for maintaining and protecting
these uses. The purpose of the OWQS
is to promote and protect as many
beneficial uses as are attainable and to
assure that degradation of existing quality
of waters of the state does not occur.
The OWQS are applicable to all activities
which may affect the water quality of
waters of the state, and are to be utilized
by all state environmental agencies in
implementing their programs to protect
water quality. Some examples of these
implementation programs are: permits
for point source (e.g. municipal and
industrial) discharges into waters of the
state; authorizations for waste disposal
from concentrated animal feeding
operations; regulation of runoff from
nonpoint sources; and corrective actions
to clean up polluted waters.
14 Central Regional Report Oklahoma Comprehensive Water Plan
North Canadian and the Little River, as well as numerous municipal and regional water supply lakes including Arcadia, Bell Cow, Chandler, Holdenville, Konawa, Meeker, Okemah, Prague City, Shawnee Twins, Stanley Draper, Stroud, Thunderbird, Tecumseh, Wes Watkins, and Wetumka. Stream salinity, although still considered high, decreases notably from the upper portions of the watersheds. The Canadian watershed is higher with a mean conductivity of 975-1,070 μS/cm on the mainstem and 1,210 on the Little River. The North Canadian is lower, with conductivity ranging from 720-850 μS/cm on the mainstem and 675-815 μS/cm on the Deep Fork. Reservoir salinity is typically low to moderate with some reservoirs ranging from 75-275 μS/cm while others have values as high as 350-450 μS/cm (Bell Cow and Thunderbird). Lake Konawa is high, with an approximate mean of 1,100 μS/cm. Stream nutrient concentrations are relatively high throughout the area and decrease at downstream sites as the watershed moves away from the Oklahoma City metropolitan area. The TP means are 0.31-0.36 ppm (Canadian), 0.68-0.94 ppm (North Canadian), and 0.19-0.34 ppm (Deep Fork). The TN means are 1.47-1.81 ppm (Canadian), 2.72-4.24 ppm (North Canadian), and 1.04-2.19 ppm (Deep Fork). The TP and TN means for Little River are relatively low at 0.16 and 0.83 ppm. While the Deep Fork and Little River remain oligotrophic, all other waters are hyper-eutrophic. All lakes are phosphorus limited and are mesotrophic or eutrophic (Arcadia, Bell Cow, Chandler, Konawa, Thunderbird, and Wes Watkins). Stream water clarity is nearly always poor to very poor and decreases downstream. Turbidity means are 52 NTU (Little River) 49-53 NTU (Canadian), 70-124 NTU (North Canadian), and 38-80 NTU (Deep Fork). Reservoir clarity is diverse and is categorized as poor (Meeker Secchi depth = 10 cm), average (Thunderbird = 53 cm), good (Prague City = 74 cm), and excellent (Stroud = 126 cm).
Dividing the Prairie Tablelands and Northern Cross Timbers is the Cross Timbers Transition. The transition is a hybrid mix of rough plains covered by prairie grasses and oak/elm and cedar forests, with cropland and rangeland as land uses.
Water Quality Impairments
A waterbody is considered to be impaired when its quality does not meet the standards prescribed for its beneficial uses. For example, impairment of the Public and Private Water Supply beneficial use means the use of the waterbody as a drinking water supply is hindered. Impairment of the Agricultural use means the use of the waterbody for livestock watering, irrigation or other agricultural uses is hindered. Impairments can exist for other uses such as Fish and Wildlife Propagation or Recreation.
The Beneficial Use Monitoring Program (BUMP), established in 1998 to document and quantify impairments of assigned beneficial uses of the state’s lakes and streams, provides information for supporting and updating the OWQS and prioritizing pollution control programs. A set of rules known as “use support assessment protocols” is also used to determine whether beneficial uses of waterbodies are being supported.
In an individual waterbody, after impairments have been identified, a Total Maximum Daily Load (TMDL) study is conducted to establish the sources of impairments—whether from point sources (discharges) or non-point sources (runoff). The study will then determine the amount of reduction necessary to meet the applicable water quality standards in that waterbody and allocate loads among the various contributors of pollution.
For more detailed review of the state’s water quality conditions, see the most recent versions of the OWRB’s BUMP Report, and the Oklahoma Integrated Water Quality Assessment Report, a comprehensive assessment of water quality in Oklahoma’s streams and lakes required by the federal Clean Water Act and developed by the ODEQ.
Water Quality Impairments
Central Region
Regional water quality impairments based on the 2008 Integrated Water Quality Assessment Report. Many surface waters in this region are impacted by urbanization, including increased nutrients and sediment as well as stream habitat alterations due to increases in impervious surfaces. Water from the Garber-Wellington (Central Oklahoma) aquifer is typically suited for public water supply but, in some areas, concentrations of nitrate, arsenic, chromium, and selenium exceed drinking water standards. Elevated concentrations of nitrate can occur in shallow water, which can be a concern for domestic well users. Elevated concentrations of arsenic, chromium, and selenium occur in deep parts of the aquifer, mostly affecting public water supply wells. The highest concentrations of arsenic tend to occur in the western portion of the aquifer where it is overlain by younger rocks.Oklahoma Comprehensive Water Plan Central Regional Report 15
In the central region, the major land use is urban, as much of the Oklahoma City metropolitan area overlays the ecoregion. Streams are typically rockier and less muddy than other streams in the region. Ecological diversity is higher than areas to the west but lower than regions to the east and is affected by habitat degradation, channelization, flow modifications, and sedimentation/siltation. The North Canadian and Canadian pass through the area and several major and minor water supply lakes exist there, including Guthrie, Liberty, Hefner, Overholser and Purcell. Stream salinity is high, ranging from 915 μS/cm (North Canadian) to 1,260 (Canadian). Lake salinity is moderate (Purcell = 400 μS/cm) to high (Hefner = 1,100 μS/cm). With the North Canadian having higher nutrient concentrations, rivers are hyper-eutrophic. The TP and TN mean concentrations range from 0.47-1.18 ppm and 2.70-4.31 ppm. All reservoirs are phosphorus limited, with the exception of Purcell Lake (eutrophic), and are hyper-eutrophic. Stream clarity is good on the North Canadian (34 NTU) but poor on the Canadian (80 NTU). Lake clarity is typically average (Liberty = 42 cm) to good (Hefner = 92 cm), but Overholser nears poor (32 cm).
The Central region is underlain by several major and minor bedrock and alluvial aquifers. In most alluvial aquifers, water quality is good with variable dissolved solid contents. Except for hardness and localized nitrate problems, alluvial groundwater is appropriate for domestic, irrigation, industrial, and municipal use. Alluvial aquifers are highly vulnerable to contamination from surface activities due to their high porosities and permeabilities and shallow water tables.
The Rush Springs aquifer borders the southern edge of the region. Although comparatively hard, most of the water derived from it is suitable for domestic, municipal, irrigation, and industrial use with total dissolved solids (TDS) values generally less than 500 ppm. However, sulfate and nitrate concentrations exceed drinking water standards in some areas.
The Garber-Wellington runs through the central portion of the region and underlies much of the Oklahoma City metropolitan area. Water ranges from hard to very hard, and in general, concentrations of dissolved solids, chloride, and sulfate are low. Water from the aquifer is normally suitable for public water supply, but concentrations of nitrates, sulfate, chloride, fluoride, arsenic, chromium, and selenium may exceed drinking water standards in localized areas.
The Vamoosa-Ada runs adjacent to the Garber-Wellington and underlies portions of Lincoln, Okfuskee, Seminole, and Pottawatomie Counties. Water quality is generally good, but iron infiltration and hardness are problems. Chloride and sulfate concentrations are generally low, and except for areas of local contamination resulting from past oil and gas activities, water is suitable for use as public supply.

Central Region16 Central Regional Report Oklahoma Comprehensive Water Plan
Special OWQS provisions in place to protect surface waters. Because Wes Watkins Reservoir and Lake Wetumka are public water supply reservoirs and have relatively small watersheds, they could potentially benefit from SWS designations. This designation could provide protection from new or increased loading from point sources in the watersheds. This additional protection would also provide limits for algae (chlorophyll a) that can cause taste and odor problems and increased treatment costs.
Surface Water Protection Areas
Central Region
Surface Water Protection
The Oklahoma Water Quality Standards (OWQS) provide protection for surface waters in many ways.
Appendix B Areas are designated in the OWQS as containing waters of recreational and/or ecological significance. Discharges to waterbodies may be limited in these areas.
Source Water Protection Areas are derived from the state’s Source Water Protection Program, which analyzes existing and potential threats to the quality of public drinking water in Oklahoma.
The High Quality Waters designation in the OWQS refers to waters that exhibit water quality exceeding levels necessary to support the propagation of fishes, shellfishes, wildlife, and recreation in and on the water. This designation prohibits any new point source discharges or additional load or increased concentration of specified pollutants.
The Sensitive Water Supplies (SWS) designation applies to public and private water supplies possessing conditions making them more susceptible to pollution events, thus requiring additional protection. This designation restricts point source discharges in the watershed and institutes a 10 μg/L (micrograms per liter) chlorophyll-a criterion to protect against taste and odor problems and reduce water treatment costs.
Outstanding Resource Waters are those constituting outstanding resources or of exceptional recreational and/or ecological significance. This designation prohibits any new point source discharges or additional load or increased concentration of specified pollutants.
Waters designated as Scenic Rivers in Appendix A of the OWQS are protected through restrictions on point source discharges in the watershed. A 0.037 mg/L total phosphorus criterion is applied to all Scenic Rivers in Oklahoma.
Nutrient Limited Watersheds are those containing a waterbody with a designated beneficial use that is adversely affected by excess nutrients.Oklahoma Comprehensive Water Plan Central Regional Report 17
Various types of protection are in place to prevent degradation of groundwater and levels of vulnerability. The Cimarron, North Canadian, and Canadian alluvial aquifers have been identified by the OWRB as highly vulnerable.
Groundwater Protection Areas
Central Region
Groundwater Protection
The Oklahoma Water Quality Standards (OWQS) sets the criteria for protection of groundwater quality as follows:
“If the concentration found in the test sample exceeds [detection limit], or if other substances in the groundwater are found in concentrations greater than those found in background conditions, that groundwater shall be deemed to be polluted and corrective action may be required.”
Wellhead Protection Areas are established by the Oklahoma Department of Environmental Quality (ODEQ) to improve drinking water quality through the protection of groundwater supplies. The primary goal is to minimize the risk of pollution by limiting potential pollution-related activities on land around public water supplies.
Oil and Gas Production Special Requirement Areas, enacted to protect groundwater and/or surface water, can consist of specially lined drilling mud pits (to prevent leaks and spills) or tanks whose contents are removed upon completion of drilling activities; well set-back distances from streams and lakes; restrictions on fluids and chemicals; or other related protective measures.
Nutrient-Vulnerable Groundwater is a designation given to certain hydrogeologic basins that are designated by the OWRB as having high or very high vulnerability to contamination from surface sources of pollution. This designation can impact land application of manure for regulated agriculture facilities.
Appendix H Limited Areas of Groundwater are localized areas where quality is unsuitable for default beneficial uses due to natural conditions or irreversible human-induced pollution. (Not shown on map.)
NOTE: Although the State of Oklahoma has a mature and successful surface water quality monitoring program, no comprehensive approach or plan to monitor the quality of the state’s groundwater resources has been developed.18 Central Regional Report Oklahoma Comprehensive Water Plan
Water Quality Trends Study
As part of the 2012 OCWP Update, OWRB monitoring staff compiled more than ten years of Beneficial Use Monitoring Program (BUMP) data and other resources to initiate an ongoing statewide comprehensive analysis of surface water quality trends. Five parameters were selected for OCWP watershed planning region analysis—chlorophyll-a, conductivity, total nitrogen, total phosphorus, and turbidity.
Reservoir Trends: Water quality trends for reservoirs were analyzed for chlorophyll-a, conductivity, total nitrogen, total phosphorus, and turbidity at sixty-five (65) reservoirs across the state. Data sets were of various lengths, depending on the station’s period of record. The direction and magnitude of trends varies throughout the state and within regions. However, when considered statewide, the final trend analysis revealed several notable details.
Chlorophyll-a and nutrient concentrations continue to increase at a number • of lakes. The proportions of lakes exhibiting a significant upward trend were 42% for chlorophyll-a, 45% for total nitrogen, and 12% for total phosphorus.
Likewise, conductivity and turbidity have trended upward over time. Nearly • 28% of lakes show a significant upward trend in turbidity, while nearly 45% demonstrate a significant upward trend for conductivity.
Stream Trends: Water quality trends for streams were analyzed for conductivity, total nitrogen, total phosphorus, and turbidity at sixty (60) river stations across the state. Data sets were of various lengths, depending on the station’s period of record, but generally, data were divided into historical and recent datasets, and analyzed separately and as a whole. The direction and magnitude of trends varies throughout the state and within regions. However, when considered statewide, the final trend analysis revealed several notable details.
Total nitrogen and phosphorus are very different when comparing period of • record to more recent data. When considering the entire period of record, approximately 80% of stations showed a downward trend in nutrients. However, if only the most recent data (approximately 10 years) are considered, the percentage of stations with a downward trend decreases to 13% for nitrogen and 30% for phosphorus. The drop is accounted for in stations with either significant upward trends or no detectable trend.
Likewise, general turbidity trends have changed over time. Over the entire • period of record, approximately 60% of stations demonstrated a significant upward trend. However, more recently, that proportion has dropped to less than 10%.
Similarly, general conductivity trends have changed over time, albeit less • dramatically. Over the entire period of record, approximately 45% of stations demonstrated a significant upward trend. However, more recently, that proportion has dropped to less than 30%.
Typical Impact of Trends Study Parameters
Chlorophyll-a is a measure of algae growth. When algae growth increases, there is an increased likelihood of taste and odor problems in drinking water as well as aesthetic issues.
Conductivity is a measure of the ability of water to pass electrical current. In water, conductivity is affected by the presence of inorganic dissolved solids, such as chloride, nitrate, sulfate, and phosphate anions (ions that carry a negative charge) or sodium, magnesium, calcium, iron, and aluminum cations (ions that carry a positive charge). Conductivity in streams and rivers is heavily dependent upon regional geology and discharges. High specific conductance indicates high concentrations of dissolved solids, which can affect the suitability of water for domestic, industrial, agricultural and other uses. At higher conductivity levels, drinking water may have an unpleasant taste or odor or may even cause gastrointestinal distress. High concentration may also cause deterioration of plumbing fixtures and appliances. Relatively expensive water treatment processes, such as reverse osmosis, are required to remove excessive dissolved solids from water. Concerning agriculture, most crops cannot survive if the salinity of the water is too high.
Total Nitrogen is a measure of all dissolved and suspended nitrogen in a water sample. It includes kjeldahl nitrogen (ammonia + organic), nitrate and nitrite nitrogen. It is naturally abundant in the environment and is a key element necessary for growth of plants and animals. Excess nitrogen from polluting sources can lead to significant water quality problems, including harmful algal blooms, hypoxia and declines in wildlife and its habitat.
Phosphorus is one of the key elements necessary for growth of plants and animals. Excess nitrogen and phosphorus lead to significant water quality problems, including harmful algal blooms, hypoxia, and declines in wildlife and its habitat. Increases in total phosphorus can lead to excessive growth of algae, which can increase taste and odor problems in drinking water as well as increased costs for treatment.
Turbidity refers to the clarity of water. The greater the amount of total suspended solids (TSS) in the water, the murkier it appears and the higher the measured turbidity. Increases in turbidity can increase treatment costs and have negative effects on aquatic communities by reducing light penetration.Oklahoma Comprehensive Water Plan Central Regional Report 19

Water Demand
The Central Region accounts for about 18% of
the total statewide water demand. Regional
demand will increase by 32% (107,250 AFY)
from 2010 to 2060. Municipal and Industrial
use will continue to be the largest demand
sector.
By 2060, Municipal and Industrial (M&I)
demand is projected to account for
approximately 58% of the Central Region’s
total demand. Currently, 62% of the region’s
M&I demand is supplied by surface water,
12% by alluvial groundwater, and 26% by
bedrock groundwater.
Crop Irrigation demand is expected to account
for 16% of the region’s total 2060 demand.
Currently, 25% of the demand from this
sector is supplied by surface water, 58% by
alluvial groundwater, and 17% by bedrock
groundwater. Predominant irrigated crops in
the Central Region include pasture grasses,
corn, and sod.
Thermoelectric Power demand is projected
to account for 14% of the total 2060 demand.
There are a number of plants using water for
thermoelectric power generation; the three
largest are Oklahoma Gas and Electric Co’s
Seminole plant and McClain Energy Facility
and InterGen North America’s Redbud Power
Plant. Currently, 89% of the demand from this
sector is supplied by surface water, 10%
by alluvial groundwater, and 1% by
bedrock groundwater.
Oil and Gas demand is projected to
account for 5% of the total 2060
demand. Currently, 68% of the
demand from this sector is
supplied by surface water, 12%
by alluvial groundwater, and
20% by bedrock groundwater.
Livestock demand is projected to account for
3% of the total 2060 demand. Currently, 26%
of the demand from this sector is supplied by
surface water, 54% by alluvial groundwater,
and 20% by bedrock groundwater. Livestock
use in the region is predominantly cattle for
cow-calf production, followed by horses, hogs,
and dairy cows.
Self-Supplied Residential demand is also
projected to account for 3% of the total 2060
demand. Currently, 71% of the demand from
this sector is supplied by alluvial groundwater
and 31% by bedrock groundwater.
Self-Supplied Industrial demand is projected
to account for 1% of the total 2060 demand.
Currently, 63% of the demand from this sector
is supplied by surface water and 37% by
bedrock groundwater.

Population and demand projection
data developed specifically for OCWP
analyses focus on retail customers for
whom the system provides direct service.
These estimates were generated from
Oklahoma Department of Commerce
population projections. In addition, the
2008 OCWP Provider Survey contributed
critical information on water production
and population serviced that was used to
calculate per capita water use. Population
for 2010 was estimated and may not
reflect actual 2010 Census values.
Exceptions to this methodology are noted.

Central Region
Water Demand
Water demand refers to the amount of water required to meet the needs of people, communities, industry, agriculture, and other users. Growth in water demand frequently corresponds to growth in population, agriculture, industry, or related economic activity. Demands have been projected from 2010 to 2060 in ten-year increments for seven distinct consumptive water demand sectors.
Water Demand Sectors
nThermoelectric Power: Thermoelectric power producing plants, using both self-supplied water and municipal-supplied water, are included in the thermoelectric power sector.
Self-Supplied Residential: Households on private wells that are not connected to a public water supply system are included in the SSR sector.
nSelf-Supplied Industrial: Demands from large industries that do not directly depend upon a public water supply system. Available water use data and employment counts were included in this sector.
nOil and Gas: Oil and gas drilling and exploration activities, excluding water used at oil and gas refineries (typically categorized as Self-Supplied industrial use), are included in the oil and gas sector.
nMunicipal and Industrial: These demands represent water that is provided by public water systems to homes, businesses, and industries throughout Oklahoma, excluding water supplied to thermoelectric power plants.
nLivestock: Livestock demands were evaluated by livestock group (beef, poultry, etc.) based on the 2007 Agriculture Census.
nCrop Irrigation: Water demands for crop irrigation were estimated using the 2007 Agriculture Census data for irrigated acres by crop type and county. Crop irrigation requirements were obtained primarily from the Natural Resource Conservation Service Irrigation Guide Reports.
OCWP demands were not projected for non-consumptive or instream water uses, such as hydroelectric power generation, fish and wildlife, recreation and instream flow maintenance. Projections, which were augmented through user/stakeholder input, are based on standard methods using data specific to each sector and planning basin.
Projections were initially developed for each county in the state, then allocated to each of the 82 basins. To provide regional context, demands were aggregated by Watershed Planning Region. Water shortages were calculated at the basin level to more accurately determine areas where shortages may occur. Therefore, gaps, depletions, and options are presented in detail in the Basin Summaries and subsequent sections. Future demand projections were developed independent of available supply, water quality, or infrastructure considerations. Impacts of climate change, increased efficiency, conservation, and non-consumptive uses, such as hydropower, are presented in supplemental OCWP reports.
Present and future demands were applied to supply source categories to facilitate an evaluation of potential surface water gaps and aquifer storage depletions at the basin level. For this baseline analysis, the proportion of each supply source used to meet future demands for each sector was held constant at the proportion established through current active water use permit allocations. For example, if the crop irrigation sector in a basin currently uses 80% bedrock groundwater, then 80% of that projected future demand is assumed to use bedrock groundwater. Existing out-of-basin supplies are represented as surface water supplies in the receiving basin and as demand on the source basin.22 Central Regional Report Oklahoma Comprehensive Water Plan
Public Water Providers
There are more than 1,600 Oklahoma water
systems permitted or regulated by the
Oklahoma Department of Environmental
Quality (ODEQ); 785 systems were analyzed
in detail for the 2012 OCWP Update. The
public systems selected for inclusion,
which collectively supply approximately 94
percent of the state’s current population,
consist of municipal or community water
systems and rural water districts that
were readily identifiable as non-profit,
local governmental entities. This and
other information provided in the OCWP
will support provider-level planning by
providing insight into future supply and
infrastructure needs.
The Central Watershed Planning Region
includes 119 of the 785 public supply systems
analyzed for the 2012 OCWP Update. The
Public Water Providers map indicates the
approximate service areas of these systems.
(The map may not accurately represent
existing service areas or legal boundaries. In
addition, water systems often serve multiple
counties and can extend into multiple
planning basins and regions.)
In terms of population served (excluding
provider-to-provider sales), the five largest
systems in the region, in decreasing order,
are Oklahoma City, Norman, Edmond PWA,
Midwest City, and Moore. Together, these
five systems serve more than 71 percent
of the combined OCWP public water
providers’ population in the region.
Demands upon public water systems, which
comprise the majority of the OCWP’s
Municipal and Industrial (M&I) water
demand sector, were analyzed at both the
basin and provider level. Retail demand
projections detailed in the Public Water
Provider Demand Forecast table were
developed for each of the OCWP providers
in the region. These projections include
estimated system
losses, defined as water
lost either during water
production or distribution
to residential homes and
businesses. Retail demands
do not include wholesaled
water.
OCWP provider demand forecasts are
not intended to supersede water demand
forecasts developed by individual providers.
OCWP analyses were made using a consistent
methodology based on accepted data available
on a statewide basis. Where available,
provider-generated forecasts were also
reviewed as part of this effort.

Public Water Provider Demand Forecast (1 of 4)
Central Region
Projections of Retail Water Demands
Each public water supply system has a “retail” demand, defined as the amount of water used by residential and non-residential customers within that provider’s service area. Public-supplied residential demands include water provided to households for domestic uses both inside and outside the home. Non-residential demands include customer uses at office buildings, shopping centers, industrial parks, schools, churches, hotels, and related locations served by a public water supply system. Retail demands do not include wholesale water to other providers.
Municipal and Industrial (M&I) demand is driven by projected population growth and specific customer characteristics. Demand forecasts for each public system are estimated from average water use (in gallons per capita per day) multiplied by projected population. Oklahoma Department of Commerce 2002 population projections (unpublished special tabulation for the OWRB) were calibrated to 2007 Census estimates and used to establish population growth rates for cities, towns, and rural areas through 2060. Population growth rates were applied to 2007 population-served values for each provider to project future years’ service area (retail) populations.
The main source of data for per capita water use for each provider was the 2008 OCWP Provider Survey conducted by the OWRB in cooperation with the Oklahoma Rural Water Association and Oklahoma Municipal League. For each responding provider, data from the survey included population served, annual average daily demand, total water produced, wholesale purchases and sales between providers, and estimated system losses.
For missing or incomplete data, the weighted average per capita demand was used for the provider’s county. In some cases, provider survey data were supplemented with data from the OWRB water rights database. Per capita supplier demands can vary over time due to precipitation and service area characteristics, such as commercial and industrial activity, tourism, or conservation measures. For the baseline demand projections described here, the per capita demand was held constant through each of the future planning year scenarios. OCWP estimates of potential reductions in demand from conservation measures are analyzed on a basin and regional level, but not for individual provider systems.28 Central Regional Report Oklahoma Comprehensive Water Plan

The OWRB provider demand forecasts are not intended to supersede demand forecasts developed by individual water providers. However, the OCWP analyses sought to use a consistent methodology based on accepted data that are available on a statewide basis. When made available, provider-generated forecasts were also reviewed as part of this effort.Oklahoma Comprehensive Water Plan Central Regional Report 31

Wholesale Water Transfers
Some providers sell water on a “wholesale” basis to other providers, effectively increasing the amount of water that the selling provider must deliver and reducing the amount that the purchasing provider diverts from surface and groundwater sources. Wholesale water transfers between public water providers are fairly common and can provide an economical way to meet demands. Wholesale quantities typically vary from year to year depending upon growth, precipitation, emergency conditions, and agreements between systems.
Water transfers between providers can help alleviate costs associated with developing or maintaining infrastructure, such as a reservoir or pipeline; allow access to higher quality or more reliable sources; or provide additional supplies only when required, such as in cases of supply emergencies. Utilizing the 2008 OCWP Provider Survey and OWRB water rights data, the Wholesale Water Transfers table presents a summary of known wholesale arrangements for providers in the region. Transfers can consist of treated or raw water and can occur on a regular basis or only during emergencies. Providers commonly sell to and purchase from multiple water providers. 32 Central Regional Report Oklahoma Comprehensive Water Plan

Public Water Provider Water Rights and Withdrawals - 2010 (1 of 4)
Central Region
Provider Water Rights
Public water providers using surface water or groundwater obtain water rights from the OWRB. Water providers purchasing water from other suppliers or sources are not required to obtain water rights as long as the furnishing entity has the appropriate water right or other source of authority. Each public water provider’s current water right(s) and source of supply have been summarized in this report. The percentage of each provider’s total 2007 water rights from surface water, alluvial groundwater, and bedrock groundwater supplies was also calculated, indicating the relative proportions of sources available to each provider.
A comparison of existing water rights to projected demands can show when additional water rights or other sources and in what amounts might be needed. Forecasts of conditions for the year 2060 indicate where additional water rights may be needed to satisfy demands by that time. However, in most cases, wholesale water transfers to other providers must also be addressed by the selling provider’s water rights. Thus, the amount of water rights required will exceed the retail demand for a selling provider and will be less than the retail demand for a purchasing provider.
In preparing to meet long-term needs, public water providers should consider strategic factors appropriate to their sources of water. For example, public water providers who use surface water can seek and obtain a “schedule of use” as part of their stream water right, which addresses projected growth and consequent increases in stream water use. Such schedules of use can be employed to address increases that are anticipated to occur over many years or even decades, as an alternative to the usual requirement to use the full authorized amount of stream water in a seven-year period. On the other hand, public water providers that utilize groundwater should consider the prospect that it may be necessary to purchase or lease additional land in order to increase their groundwater rights.Oklahoma Comprehensive Water Plan Central Regional Report 35

Central Region
Provider Supply Plans
In 2008, a survey was sent to 785 municipal and rural water providers throughout Oklahoma to collect vital background water supply and system information. Additional detail for each of these providers was solicited in 2010 as part of follow-up interviews conducted by the ODEQ. The 2010 interviews sought to confirm key details of the earlier survey and document additional details regarding each provider’s water supply infrastructure and plans. This included information on existing sources of supply (including surface water, groundwater, and other providers), short-term supply and infrastructure plans, and long-term supply and infrastructure plans.
In instances where no new source was identified, maintenance of the current source of supply is expected into the future. Providers may or may not have secured the necessary funding to implement their stated plans concerning infrastructure needs, commonly including additional wells or raw water conveyance, storage, and replacement/upgrade of treatment and distribution systems.
Additional support for individual water providers wishing to pursue enhanced planning efforts is documented in the Public Water Supply Planning Guide. This guide details how information contained in the OCWP Watershed Planning Region Reports and related planning documents can be used to formulate provider-level plans to meet present and future needs of individual water systems. 38 Central Regional Report Oklahoma Comprehensive Water Plan
